S100, in response to the light source component emitting a target light beam into the gain medium cavity, obtaining the initial atomic level E' that pops out of the gain medium cavity; wherein the wavelength of the target light beam emitted by the light source component is controlled by the current corresponding to the light source component.

In this embodiment, the light beam output device can be understood as a semiconductor laser, the light source component can be understood as a component for generating pump light, the light source component emits a light beam to the gain medium in the gain medium cavity, the gain medium is a semiconductor material, that is, the gain medium material described in the present application, and the gain medium will jump out of the initial atomic level under the action of the light beam emitted by the light source component, and the initial atomic level will generate laser through stimulated radiation of subsequent reflectors; when the initial atomic level jumps out of the gain medium cavity, the initial atomic level can be obtained; it should be noted that the wavelength of the light beam emitted by the light source component is fixed, and the wavelength can be controlled by the input current of the light source component; the atomic level is the transition energy during atomic transition.

S200, according to a preset gain medium material attribute list, obtaining the atomic weight level corresponding to each gain medium material at the wavelength of the target light beam to obtain an atomic weight level list E=( _E1 , _E2 , …, _Ei , …, _En ), i=1, 2, …, n; wherein _Ei is the atomic weight level corresponding to the i-th gain medium material in the gain medium material attribute list, and n is the number of gain medium materials in the gain medium material attribute list; the gain medium material attribute list includes p rows and q columns, each row corresponds to a gain medium material, and each column corresponds to an attribute of a gain medium material; the attribute of the gain medium material includes the atomic weight level corresponding to the gain medium material.

In this embodiment, the preset gain medium material attribute list includes p kinds of gain medium materials, and each gain medium material corresponds to a number of attributes, for example, the atomic level of a certain gain medium material under the irradiation of the target light beam, the temperature under the irradiation of the target light beam, etc.; for each gain medium material, the corresponding atomic level can be obtained in advance under the target light beam; the atomic level corresponding to each gain medium material in the gain medium material attribute list under the wavelength of the target light beam can be obtained to obtain E.

S300, traverse E, if |E'-E _i |＜ΔE, then determine the gain medium material corresponding to E _i as the intermediate gain medium material to obtain an intermediate gain medium material list W=(W ₁ , W ₂ , …, W _j , …, W _m ), j=1, 2, …, m; wherein W _j is the jth intermediate gain medium material determined, m is the number of the intermediate gain medium materials determined; ΔE is a preset atomic weight level difference threshold.

In this embodiment, the preset atomic weight level difference threshold can be obtained by performing multiple tests on a number of gain medium materials. It can be understood that even for the same gain medium material, the atomic weight levels that pop out are different under different conditions. Therefore, in this embodiment, the number of intermediate gain medium materials obtained is not a fixed value.

S400: If m=1, determine _W1 as the gain medium material corresponding to the gain medium in the gain medium cavity.

It can be understood that if m=1, it means that only one intermediate gain medium material is determined, and the intermediate gain medium material can be directly determined as the gain medium material corresponding to the gain medium, thereby achieving the purpose of determining which gain medium material the gain medium is.

Furthermore, after step S400, the control device is further configured to perform the following steps:

S500, if m＞1, then control the current corresponding to the light source component to increase to obtain a plurality of increasing currents; wherein, when the light source component inputs each increasing current, an intermediate atomic level can pop out of the gain medium cavity to generate a corresponding intermediate light beam.

In this embodiment, if m>1, it means that there are multiple intermediate gain medium materials determined, and there are multiple gain medium materials that are relatively similar to the actual gain medium material of the gain medium, and it is necessary to determine the gain medium material actually corresponding to the gain medium by other means; specifically, the size of the input current corresponding to the light source component is changed so that the input current corresponding to the light source component is increased to obtain a number of increasing currents; for example, the initial current of the light source component is 20 mA, and the input current of the light source component is increased to 25 mA, 30 mA, etc.; under each increasing current, the intermediate atomic mass levels that pop out of the gain medium cavity generate corresponding intermediate light beams.

S510, obtaining the wavelength of each intermediate light beam and the temperature of the gain medium when generating each intermediate light beam, so as to obtain an intermediate light beam wavelength-temperature list set Y=(Y ₁ , Y ₂ , …, Y _r , …, Y _k ), r=1, 2, …, k; wherein Y _r is the intermediate light beam wavelength-temperature list corresponding to the r-th current obtained, and k is the number of intermediate light beam wavelength-temperature lists obtained; Y _r =(Y _{r, 1} , Y _{r, 2} ), Y _{r, 1} is the wavelength of the r-th intermediate light beam, and Y _{r, 2} is the temperature of the gain medium when generating the r-th intermediate light beam.

It can be understood that under different input currents, the temperature corresponding to the gain medium is also different. When the temperature of the gain medium is different, the wavelength of the light emitted from the gain medium will undergo a red shift, causing the wavelength of the light to deviate from the actual wavelength; based on this, Y can be obtained.

S520. Determine the temperature fluctuation rate of the intermediate light beam wavelength corresponding to the gain medium according to Y to obtain a list of temperature fluctuation rates of the intermediate light beam wavelength α=(α ₁ , α ₂ , …, α _h , …, α _k-1 ), h=1, 2, …, k-1; wherein α _h is the hth temperature fluctuation rate of the intermediate light beam wavelength corresponding to the gain medium; α _h =(Y _h+1 , 1 -Y _{h, 1} )/(Y _{h+1, 2} -Y _{h, 2} ).

S530, determining the temperature fluctuation rate of the target light beam wavelength corresponding to the gain medium α'=∑ ^k-1 _h=1 α _h according to α.

In this embodiment, the target light beam wavelength temperature fluctuation rate is obtained by averaging a plurality of intermediate light beam wavelength temperature fluctuation rates, thereby avoiding the situation where a sudden change in a certain data causes an inaccurate target light beam wavelength temperature fluctuation rate.

S540, determining a gain medium material corresponding to the gain medium according to α' and a preset gain medium material attribute list; wherein the attributes of the gain medium material in the gain medium material attribute list further include a corresponding light beam wavelength temperature fluctuation rate.

In this embodiment, the preset gain medium material property list also includes the known light beam wavelength temperature fluctuation rate corresponding to each gain medium material; the light beam wavelength temperature fluctuation rate corresponding to each gain medium material can be obtained in advance through a large number of experiments, or can be calculated by referring to the specific characteristics of each semiconductor material.

Further, step S540 includes the following steps:

S541, obtaining the light beam wavelength temperature fluctuation rate corresponding to each gain medium material in the gain medium material attribute list to obtain an initial light beam wavelength temperature fluctuation rate set β=(β ₁ , β ₂ , …, β _e , …, β _p ), e=1, 2, …, p; wherein β _e is the light beam wavelength temperature fluctuation rate corresponding to the e-th gain medium material in the gain medium material attribute list.

S542, traverse β, if |α'-β _e |＜Δβ, determine the gain medium material corresponding to β _e as the gain medium material corresponding to the gain medium; wherein Δβ is a preset light beam wavelength temperature fluctuation rate difference threshold.

In this embodiment, if |α'-β _e |＜Δβ, it means that the light beam wavelength temperature fluctuation rate of the gain medium material corresponding to β _e is closest to the light beam wavelength temperature fluctuation rate corresponding to the actual gain medium material of the gain medium, and the gain medium material corresponding to β _e can be determined as the gain medium material corresponding to the gain medium; in this embodiment, since the target light beam wavelength temperature fluctuation rate is obtained by averaging a plurality of intermediate light beam wavelength temperature fluctuation rates, the situation that the target light beam wavelength temperature fluctuation rate is inaccurate due to a certain data mutation is avoided, thereby making the determined gain medium material corresponding to the gain medium more accurate.

Furthermore, after step S400, the control device is further configured to perform the following steps:

S600, if m=0, increase the current _I1 corresponding to the light source component to _I2 , so that the light source component emits a light beam into the gain medium cavity at the current _I2 ; wherein _I1 corresponds to E'.

In this embodiment, if m=0, it means that the difference between the atomic level in the gain medium material attribute list and the initial atomic level is greater than or equal to ΔE, and the gain medium material corresponding to the gain medium cannot be determined; at this time, the input current of the light source component needs to be increased to I ₂ .

S610, obtaining the atomic level E' ₁ popped out of the gain medium cavity when the current corresponding to the light source component is I ₂ .

S620, determining the current atomic level change rate TG corresponding to the gain medium according to I ₁ , I ₂ , E' and E' ₁ = (E' ₁ -E')/(I ₂ -I ₁ ).

S630, determining a target gain medium material corresponding to the gain medium according to TG and a preset gain medium material attribute list; wherein the attribute of the gain medium material in the gain medium material attribute list further includes a corresponding current atomic level change rate.

Specifically, the current atomic level change rate corresponding to each gain medium material in the gain medium material attribute list can be obtained, and then the difference between TG and the current atomic level change rate corresponding to each gain medium material in the gain medium material attribute list is calculated, and the gain medium material corresponding to the current atomic level change rate whose difference is within a preset range is determined as the gain medium material corresponding to the gain medium; in addition, if the number of gain medium materials corresponding to the determined gain medium is greater than 1, the gain medium material corresponding to the gain medium can be accurately determined by the method in steps S500-S540.

Furthermore, after step S400, the control device is further configured to perform the following steps:

S700: Obtain a membership function type corresponding to a target gain medium material from a preset gain medium material attribute list.

S711, controlling the temperature of the gain medium using the membership function type corresponding to the target gain medium material.

In this embodiment, when the semiconductor laser is working, it is usually necessary to accurately control the temperature of the gain medium to avoid the red shift phenomenon. In the above embodiment, after determining the target gain medium material corresponding to the gain medium, the membership function corresponding to the target gain medium material can be selected to control the temperature of the gain medium to achieve a better temperature control effect.

The gain medium material determination method of the present embodiment obtains the initial atomic level that pops out of the gain medium cavity, and the initial atomic level corresponds to a fixed current; the initial atomic level is compared with each atomic level in a preset gain medium material attribute list, and if the difference between a certain atomic level in the gain medium material attribute list and the initial atomic level is less than a preset atomic level difference threshold, the gain medium material corresponding to the atomic level is determined as the gain medium material corresponding to the gain medium, thereby achieving the purpose of determining which gain medium material the gain medium is, and then selecting a control strategy for laser generation according to the determined specific gain medium material attribute, so that the wavelength of the generated laser has a higher accuracy.

In an exemplary embodiment, a method for determining a membership function type corresponding to a target gain medium material is provided, the method comprising the following steps:

S710, obtaining an initial temperature vector corresponding to the target gain medium material when emitting light in each preset time period, to obtain an initial temperature vector list A=( _A1 , _A2 , ..., _Ae , ..., _Au ), e=1, 2, ..., u; wherein _Ae is the initial temperature vector corresponding to the target gain medium material when emitting light in the e-th time period, and u is the number of preset time periods; _Ae =(Ae _{, 1} , Ae _{, 2} , Ae _{, 3} , Ae _{, 4} , Ae _{, 5} ); Ae _{, 1} is the average room temperature corresponding to the target gain medium material when emitting light in the e-th time period, Ae _{, 2} is the maximum temperature when the target gain medium material emits light in the e-th time period, Ae _{, 3} is the power change rate when the target gain medium material emits light in the e-th time period, Ae _{, 4} is the wavelength of the light beam generated by the target gain medium material when emitting light in the e-th time period, and Ae _{, 5} is the average power when the target gain medium material emits light in the e-th time period; the initial temperature of the target gain medium material when emitting light in each time period is the same.

In this embodiment, the input current of the light source component is set to a preset fixed current, and a light beam is generated to the target gain medium material corresponding to the gain medium. The target gain medium material will correspond to several parameters when emitting light, and the average room temperature, maximum temperature, power change rate, wavelength of the generated light beam and average power of the target gain medium material when emitting light in each preset time period can be obtained; it should be noted that the duration of each preset time period is the same, for example, the duration of the time period is 10 minutes, 20 minutes or 1 hour, etc.; the average room temperature can be determined by collecting multiple room temperatures in each time period and then calculating the average value; the maximum temperature of the target gain medium material can be determined by collecting multiple temperatures of the target gain medium material in each time period and then calculating the maximum temperature; the power change rate and the average power can be determined by obtaining multiple powers corresponding to the gain medium material when emitting light, calculating the average of the multiple powers, determining the average power, and then obtaining the maximum power and the minimum power to determine the power change rate; the wavelength of the light beam can be determined by obtaining the wavelengths of multiple light beams and calculating the average value; it should be noted that the initial temperature of the target gain medium material when emitting light in each time period can be the same by cooling.

S720, normalize each temperature vector in A to obtain an intermediate temperature vector list A'=( _A'1 , _A'2 , ..., _A'e , ..., _A'u ); wherein _A'e is the intermediate temperature vector corresponding to _Ae ; _A'e =(A'e _,1 , A'e _,2 , A'e _,3 , A'e _,4 , A'e _,5 ); A'e _,1 is the normalized value corresponding to Ae _,1, A'e _,2 is the normalized value corresponding to Ae,2, A'e _,3 is the normalized value corresponding to Ae, ₃ , A'e _{,4 is} the normalized value corresponding to _Ae,4, and A'e _,5 is the normalized value corresponding to Ae _, 5; A'e _,1 =Ae _,1 /maxAe _,1 ; A'e _,2 =Ae _,2 /maxAe _,2 ; A'e _,3 =Ae _,3 /maxAe _,3 ; A'e _,4 =Ae _,4 /maxA _e,4 ;A' _e,5 =A _e,5 /maxA _e,5 ; maxA _e,1 is the maximum average room temperature among all the average room temperatures in A, maxA _e,2 is the maximum value among all the maximum temperatures in A, maxA _e,3 is the maximum power change rate among all the power change rates in A, maxA _e,4 is the maximum wavelength among all the wavelengths in A, maxA _e,5 is the maximum average power among all the average powers in A.

S730. According to A', obtain the evaluation value corresponding to each intermediate temperature vector to obtain an evaluation value list MA=(MA ₁ , MA ₂ , …, MA _e , …, MA _u ); wherein MA _e is the evaluation value corresponding to A'_e; MA _e =(A' _{e, 1} +A' _{e, 2} +A' _{e, 3} +A' _{e, 4} +A' _{e, 5} )/5.

In this embodiment, it can be understood that the values of the elements in each intermediate temperature vector are all in the range of 0 to 1. Therefore, the evaluation value corresponding to each intermediate temperature vector is in the range of 0 to 1. Therefore, each intermediate temperature vector can be better judged by the evaluation value.

S740, using a preset clustering algorithm, cluster all the intermediate temperature vectors in A' into y clusters to obtain a cluster list B=( _B1 , _B2 , …, _Bx , …, _By ), x=1, 2, …, y; wherein, _Bx is the x-th cluster obtained by clustering all the intermediate temperature vectors in A'; _Bx =(Bx _{, 1} , Bx _{, 2} , …, Bx _{, ε} , …, Bx _{, f(x)} ), ε=1, 2, …, f(x); Bx _{, ε} is the ε-th intermediate temperature vector in the x-th cluster obtained by clustering all the intermediate temperature vectors in A', and f(x) is the number of intermediate temperature vectors in _Bx .

In this embodiment, the preset clustering algorithm can be a DBSCAN clustering algorithm, which is an unsupervised clustering algorithm. It does not require a preset number of clusters and has a better clustering effect. It can be understood that the similarity between all intermediate temperature vectors in each cluster is relatively high. The more intermediate temperature vectors in a cluster, the closer the working state of the target gain medium material is to the working state of the target gain medium material represented by the intermediate temperature vectors in the cluster as a whole.

S750, obtaining the number of vectors in each cluster to obtain a list of the number of vectors in the cluster corresponding to B, NUM=( _NUM1 , _NUM2 , ..., _NUMx , ..., _NUMy ); wherein _NUMx is the number of intermediate temperature vectors in _Bx .

In this embodiment, through the above steps, each cluster is converted into a point, and each point is associated with the number and evaluation value of the corresponding intermediate temperature vectors in the cluster, so as to facilitate the subsequent construction of a reference curve corresponding to the target gain medium material.

S770: Determine the type of membership function corresponding to the target gain medium material according to NUM and MB.

In this embodiment, step S770 includes the following steps:

S771, determine the coordinates corresponding to each cluster in B in the preset rectangular coordinate system according to NUM and MB, to obtain a cluster coordinate list ZB=( _ZB1 , _ZB2 , ..., _ZBx , ..., _ZBy ); wherein _ZBx is the coordinate corresponding to _Bx ; _ZBx =(ZBx _{, 1} , ZBx _{, 2} ); ZBx _{, 1} is the horizontal coordinate corresponding to _Bx in the preset rectangular coordinate system, and ZBx _{, 2} is the vertical coordinate corresponding to _Bx in the preset rectangular coordinate system; _{ZBx, 1} = _MBx , ZBx _{, 2} = _NUMx .

S772, in a rectangular coordinate system, fitting each coordinate in ZB to generate a reference curve QX corresponding to the target gain medium material.

In this embodiment, it should be noted that those skilled in the art can adopt existing curve fitting methods according to actual needs to fit each coordinate in ZB to generate a reference curve QX corresponding to the target gain medium material, which will not be elaborated here.

S773, obtaining the similarity between QX and the membership function curve corresponding to each known type of membership function to obtain a similarity list TY=(TY ₁ , TY ₂ , …, TY _η , …, TY _δ ), η=1, 2, …, δ; wherein TY _η is the similarity between QX and the membership function curve corresponding to the ηth known type of membership function, and δ is the number of known membership function types.

In this embodiment, membership function curves corresponding to several membership functions of known types can be obtained in advance, for example, Gaussian membership function, generalized bell-shaped membership function, triangular membership function, etc.; the shape of the membership function curve corresponding to each membership function is different, and the similarity between QX and the membership function curve corresponding to each known membership function can be obtained to obtain TY; it should be noted that those skilled in the art can adopt the existing curve similarity acquisition method according to actual needs to obtain the similarity between QX and the membership function curve corresponding to each known type of membership function, which will not be elaborated here.

S774, obtaining target similarity MTY=MAX(TY); wherein MAX() is a preset maximum value function.

S775: Determine the membership function type corresponding to the MTY as the membership function type corresponding to the target gain medium material.

In this embodiment, the type of membership function used in temperature control is determined according to the actual target gain medium material corresponding to the gain medium, which can avoid the problem of poor temperature control accuracy caused by the membership function selected in temperature control not being consistent with the gain medium material actually corresponding to the gain medium, thereby improving the accuracy of gain medium temperature control.

Furthermore, in this embodiment, the corresponding membership function type can be determined for each existing gain medium material according to the method in the above embodiment, and the membership function type corresponding to each gain medium material is added to the preset gain medium material attribute list. In the subsequent temperature control, the corresponding membership function can be directly selected according to the different gain medium materials corresponding to the gain medium, so as to improve the accuracy of the gain medium temperature control.

In an exemplary embodiment, in order to achieve a better temperature control effect, a method for determining the domain of a membership function corresponding to a target gain medium material is provided, the method comprising the following steps:

S700, sort the evaluation values in MB in ascending order to obtain a sorted evaluation value list MB'=(MB' ₁ , MB' ₂ , …, MB' _s , …, MB' _y ) corresponding to B, s=1, 2, …, y; wherein MB' _s is the sth evaluation value obtained by sorting the evaluation values in MB in ascending order.

S710: If the type of the membership function corresponding to the target gain medium material is a Gaussian membership function, and y is an odd number, MBʹ is determined as the domain of the membership function corresponding to the target gain medium material.

In this embodiment, the domain of the membership function corresponding to the target gain medium material is determined according to the evaluation value corresponding to each cluster. Compared with determining the domain of the membership function based on experience, it is more reliable and the determination of the domain is more reasonable. In addition, the evaluation value corresponding to each cluster is converted according to the initial temperature vector and is closely related to the temperature characteristics of the target gain medium material. Therefore, the domain of the membership function determined by the method in this embodiment makes the temperature control more accurate in the subsequent temperature control process.

Furthermore, after step S710, the method further includes the following steps:

S720: If the membership function corresponding to the target gain medium material is a Gaussian membership function and y is an even number, obtain an expansion value KB=(MB'y _/2 +MB'y _/2+1 )/2.

It is understandable that the number of elements in the domain of the Gaussian membership function is an odd number, while in the present application, the number of clusters y obtained by clustering may be an even number. When y is an even number, y cannot be directly determined as the number of elements in the domain of the membership function, and another center point KB needs to be added.

S730, adding KB to MB' between MB'y _/2 and MB'y _/2+1 in MB' to obtain an expanded evaluation value list.

S740: Determine the expanded evaluation value list as the domain of the membership function corresponding to the target gain medium material.

In this embodiment, through the above method, even if the membership function corresponding to the target gain medium material is a Gaussian membership function and y is an even number, the evaluation value list can be expanded to the domain of the membership function, thereby improving the flexibility of determining the domain of the membership function.

Furthermore, after step S710, the method further includes the following steps:

S750: If the membership function corresponding to the target gain medium material is not a Gaussian membership function, each evaluation value in MB' is determined as an element in the domain of the membership function corresponding to the target gain medium material.

In this embodiment, the membership functions other than the Gaussian membership function are asymmetric functions, and the elements in the corresponding domain do not necessarily have to be odd numbers. Therefore, each evaluation value in MB’ can be determined as an element in the domain of the membership function corresponding to the target gain medium material.

In an exemplary embodiment, after determining the target gain medium material and the type of membership function corresponding to the gain medium, the temperature of the gain medium can be controlled, specifically including the following steps:

In this embodiment, the preset gain medium material attribute list includes p types of gain medium materials, and each gain medium material corresponds to a number of attributes, for example, the atomic level of a certain gain medium material under the irradiation of the target light beam, the temperature under the irradiation of the target light beam, and the corresponding membership function type, etc.; for each gain medium material, the corresponding membership function type can be determined in advance.

S3, determining the membership function type corresponding to the target gain medium material as the membership function type corresponding to the temperature controller, and determining the membership function corresponding to the temperature controller according to the determined membership function type, so as to control the temperature of the gain medium through the membership function corresponding to the temperature controller.

In this embodiment, it should be noted that those skilled in the art can adopt the existing fuzzy control method and the determined membership function type to control the temperature of the gain medium according to actual needs, which will not be elaborated here.

S4, obtaining the current temperature deviation ρ and the temperature deviation change rate ρ _c of the gain medium controlled by the temperature controller; wherein ρ=T ₁ -T ₂ ; T ₁ is the set temperature of the gain medium, T ₂ is the current actual temperature of the gain medium; ρ _c =(ρ-ρ')/TU;ρ' is the temperature deviation of the last measurement adjacent to ρ, and TU is the time interval between two adjacent temperature measurements.

In this embodiment, during the temperature control process of the gain medium, there are corresponding set temperatures and actual temperatures, thereby the current temperature deviation can be determined, and the temperature deviation change rate can be determined according to the time interval between two adjacent temperature measurements.

S5. If ρ＞DU or ρ _c ＞TE, obtain the first performance value GT ₁ , the second performance value GT ₂ , the third performance value GT ₃ and the fourth performance value GT ₄ of the temperature controller; wherein DU is the temperature deviation threshold value corresponding to the target gain medium material, and TE is the temperature deviation change rate threshold value corresponding to the target gain medium material; GT ₁ is the performance value of the temperature controller corresponding to the time multiplied absolute error integral criterion, GT ₂ is the performance value of the temperature controller corresponding to the absolute error integral criterion, GT ₃ is the performance value of the temperature controller corresponding to the time multiplied square error integral criterion, and GT ₄ is the performance value of the temperature controller corresponding to the square error integral criterion.

In this embodiment, the temperature deviation and temperature deviation change rate of the gain medium may be obtained at preset time intervals, and then compared with the temperature deviation threshold and the temperature deviation change rate threshold, respectively, to determine whether the performance of the temperature controller needs to be evaluated.

It should be noted that those skilled in the art can respectively determine GT ₁ , GT ₂ , GT 3 and GT ₄ by using the existing time multiplied absolute error integration criterion, absolute error integration criterion, time multiplied square error integration criterion and square error integration criterion according to actual _needs , which will not be elaborated here.

Specifically, DU is determined by the following steps:

S51 , according to A, obtaining the maximum temperature of the target gain medium material in each preset time period to obtain a maximum temperature list HT=(A _1,2 , A _2,2 , …, A _e,2 , …, _Au,2 ).

S52, according to HT, obtain the temperature deviation of the target gain medium material in each preset time period to obtain a temperature deviation list KT=(KT ₁ , KT ₂ , …, KT _e , …, KT _u ); wherein KT _e is the temperature deviation of the target gain medium material in the e th preset time period; KT _e =SF-A _e,2 ; SF is the standard temperature.

In this embodiment, a fixed current can be input into a semiconductor laser based on a target gain medium material so that it can generate laser light normally. During the process of the semiconductor laser generating laser light, the maximum temperature of the target gain medium material in each preset time period can be obtained. When a fixed current is input into the semiconductor laser, the target gain medium material corresponds to a theoretical standard temperature SF.

S53, according to KT, determine DU=1/u×∑ ^ue ₌₁ KT _e .

In this embodiment, DU is determined based on the maximum temperatures within a plurality of preset time periods, thereby preventing a sudden change in a certain maximum temperature from causing inaccurate DU.

Specifically, TE is determined by the following steps:

S54, according to KT, obtain the temperature deviation change rate between two adjacent preset time periods to obtain a temperature deviation change rate list LT=(LT ₁ , LT ₂ , …, LT _v , …, LT _u-1 ), v=1, 2, …, u-1; wherein LT ₁ is the temperature deviation change rate between KT ₁ and KT ₂ ; LT _v =(KT _v+1 -KT _v )/PU; PU is the time interval between two adjacent preset time periods.

S55, according to LT, determine TE=(1/u-1)×∑ ^u-1 _v=1 LT _v .

In this embodiment, LT is determined based on a plurality of temperature deviation change rates, thereby avoiding the problem that a certain temperature deviation change rate has a large error and thus causes inaccurate LT.

It should be noted that DU and LT in this embodiment are obtained based on the temperature characteristics of the target gain medium material during its working process. Compared with directly setting the threshold value based on experience, DU and LT determined by the method in this embodiment are more reasonable and can better match the temperature characteristics of the target gain medium material during its actual working process, thereby improving the accuracy of the judgment.

S6. If GT ₁ > WQ ₁ , GT ₂ > WQ ₂ , GT ₃ > WQ ₃ or GT ₄ > WQ ₄ , the parameters of the membership function corresponding to the temperature controller are optimized; wherein WQ ₁ is the performance threshold corresponding to the preset time multiplied absolute error integral criterion, WQ ₂ is the performance threshold corresponding to the preset absolute error integral criterion, WQ ₃ is the performance threshold corresponding to the preset time multiplied square error integral criterion, and WQ ₄ is the performance threshold corresponding to the preset square error integral criterion.

In this embodiment, WQ ₁ , WQ ₂ , WQ ₃ and WQ ₄ can be determined based on experience. If GT ₁ > WQ ₁ , GT ₂ > WQ ₂ , GT ₃ > WQ ₃ or GT ₄ > WQ ₄ , it means that the current performance of the temperature controller cannot meet the preset conditions. At this time, it is necessary to optimize the parameters of the membership function corresponding to the temperature controller. For example, the particle swarm algorithm can be used to optimize the parameters of the membership function again.

The gain medium material temperature control method of this embodiment obtains the current temperature deviation and the temperature deviation change rate during the temperature control of the gain medium. If the current temperature deviation is greater than the temperature deviation threshold or the temperature deviation change rate is greater than the temperature deviation change rate threshold, it indicates that the current temperature control is inaccurate. Then, the first performance value GT ₁ , the second performance value GT ₂ , the third performance value GT ₃ and the fourth performance value GT ₄ of the temperature controller are obtained, and then compared with the corresponding performance thresholds respectively. If any performance value is greater than the corresponding performance threshold, it indicates that the performance of the current temperature controller has declined, and the parameters of the membership function corresponding to the temperature controller need to be optimized to enable the temperature controller to maintain good performance, thereby improving the accuracy of the gain medium temperature control.
