Referring to fig. 1-3, an embodiment of the invention provides a laser 100, which includes a housing 110 having a laser channel 110a, a semiconductor array module, and a collecting mirror 120, a total reflection mirror 130, a working substance 140, a Q-switched crystal 150, and a half reflection mirror 160, all of which are accommodated in the laser channel 110a and arranged along an extending direction of the laser channel 110 a. The semiconductor array component is used for emitting pump light, the converging mirror 120 is used for converging pump light in a scattering state generated by the semiconductor array component, the working substance 140 is used for realizing energy level transition of the pump light, the total reflection mirror 130 is used for allowing the pump light without energy level transition to pass through and reflecting the pump light after the energy level transition, the Q-switched crystal 150 is used for compressing the pump light after the energy level transition, and the half reflection mirror 160 is used for reflecting part of the pump light after the energy level transition and outputting part of the pump light after the energy level transition.
When the laser 100 provided in the above embodiment is used, after the semiconductor array component emits the scattered 808nm pump light, the collecting mirror 120 collects the scattered 808nm pump light, and transmits the 808nm pump light to the holophote 130.
Based on the characteristics of the all-mirror 130 for passing a specific beam and reflecting other specific beams, the 808nm pump light passes through the all-mirror 130 and is guided into the working substance 140. The pump light of 808nm realizes energy level transition in the working substance 140 and is converted into pump light of 1064 nm. After passing through the action of the Q-tuning crystal 150, it reaches the half mirror 160. The half mirror 160 outputs part of the 1064nm pump light, and the rest is reflected back to the full mirror 130. The all-mirror 130 and the half-mirror 160 form an oscillation cavity, and the 1064nm pump light oscillates in the oscillation cavity and is continuously output from the half-mirror 160.
By adopting the laser 100 provided by the embodiment, the structure is relatively simple, and related structures such as a bracket are avoided, so that the problems of large volume and heavy mass of the laser 100 in the prior art are solved.
It should be noted that, in this embodiment, the surface of the total reflection mirror 130 is plated with an antireflection film of 808nm and a total reflection film of 1064nm, so that the functions mentioned in the above embodiments can be implemented.
The working substance 140 is one of the important components in the laser apparatus and may be a gas, a liquid, a solid, or a semiconductor. Population inversion can be achieved in such media to create the necessary conditions for obtaining laser light. It is clear that the presence of metastable energy levels is very advantageous for achieving population inversion. The existing working media are nearly thousands of, and the laser wavelengths which can be generated comprise vacuum ultraviolet to far infrared, which is very extensive.
The Q-switched crystal 150, called Q-switch, is a technique for compressing the continuous laser energy output generally into pulses with extremely narrow widths for emission, so that the peak power of the light source can be increased by several orders of magnitude.
Referring to fig. 1-3, in an embodiment, the housing 110 includes a body 112 having a laser channel 110a and a first cover 114 covering the laser channel 110a, and the converging mirror 120 is located at an end of the laser channel 110a close to the first cover 114.
With the housing 110 provided in this embodiment, the installation of the converging mirror 120 is relatively simple. Furthermore, the converging mirror 120 is disposed at the end of the housing 110, so that the laser 100 can be more compact.
In a specific embodiment, the laser 100 further includes a pressing ring 170, and the pressing ring 170 is attached to the inner wall of the first cover 114 and abuts against the converging mirror 120.

In one embodiment, the housing 112 is recessed near an end of the second cover 116 to form a receiving slot, and the Q-switched crystal 150 is received in the receiving slot.
In this manner, not only is installation convenient, but the Q-switched crystal 150 can be positioned in the laser channel 110 a.
In a more specific embodiment, the laser 100 further includes a pressing cover 190, and the pressing cover 190 abuts against an end of the Q-switching crystal 150 close to the second cover 116 and is fixedly connected to the housing 112.
In other embodiments, the Q-switched crystal 150 may be fixed in the receiving groove by tight abutment.
In a more specific embodiment, the second cover 116 has a receiving groove communicating with the receiving groove, and the half mirror 160 is received and fixed in the receiving groove.
It should be noted that, by adopting the design of the housing 110 provided in this embodiment, the half mirror 160 and the Q-switched crystal 150 can be separately assembled, which facilitates the design of the mounting structure of the half mirror 160 and the Q-switched crystal 150.
