Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
Carving processing, has the requirement of two aspects to laser beam, a requirement is laser beam in being realized inside transparent material
It is able to must be deep into inside transparent material, another requirement is that, in ad-hoc location, laser beam can produce phase with transparent material
Interaction, changes the refractive index of transparent material, realizes so-called interior carving.Typically there are two kinds of Basic Ways to change organic transparent
A kind of refractive index of plastics, method utilizes strong laser field, makes the transient evaporation of organic plastics, so as to produce cavity, forms interior carving
Effect.But because the generation of strong laser field depends on femto-second laser, this method is also simply used in the lab at present.It is another
It is the method for utilizing heating to plant, and makes transparent plastic regelation, condensing zone and the plastics of surrounding can be produced caused by stress structure
Raw refractive index difference.
For relying on the organic plastics that is processed of fuel factor, select suitable optical maser wavelength turn into one it is important
Step.The output wavelength of conventional laser is general in 1 micron of (Nd at present:YAG laser or ytterbium-doping optical fiber laser) near,
Organic transparent plastic absorbs seldom to it, it is impossible to directly process, and CO2The output wavelength of laser is organic near 10 microns
Transparent plastic absorbs very big to it, can be used only in the Surface Machining of organic plastics.
According to problems of the prior art, the too small absorption that can cause organic transparent plastic to wavelength of wavelength is seldom,
It can not be processed；Wavelength, which crosses conference, causes absorption of organic transparent plastic to wavelength excessive, is only used for the table of organic plastics
Face is processed, therefore, and it is a most important step to select suitable optical maser wavelength.Based on the laser for mixing Thulium lasers medium,
Including optical fiber laser and solid state laser, its output wavelength near 2 microns, it is most of 1.9 microns~2.1 microns it
Between, it is a most suitable selection for processing organic transparent plastic.By taking lucite (acrylic or PMMA) as an example, 2
Its absorption coefficient of micron waveband is general in 1.0/mm or so.The laser beam of 2 micron wave lengths passes through the thick lucite of 2mm, about
20% or so is absorbed, therefore may be used as carrying out lucite interior carve.
After it have chosen suitable optical maser wavelength, it is still necessary to solve in the case where not interfering with peripheral plastic property,
The problem of position specified is heated to organic transparent plastic.The utility model uses the method that multiple beam (light beam number N) is focused on, and makes
The light intensity obtained in focus meet is N times of the light intensity of laser beam in single-pathway, when the plastic warm caused by the light intensity of laser
When degree is higher than the glass transition point of plastics (for acrylic plastics, the temperature of glass transition point is 104 DEG C), plastics will melt
Change.After laser is turned off, plastics regelation again forms refringence dissimilarity, realizes the interior carving to organic transparent plastic.Due to
Light intensity on the path of single light beam only has the 1/N of focal point light intensity, and the temperature caused by it is less than the glass transition of plastics
Point, will not produce influence, so as to remain in that the transparent characteristic of plastics in non-designated position to transparent plastic.
The concrete structure schematic diagram for the transparent plastic engraving device that the utility model is provided, as shown in figure 1, including for holding
Carry the translation stage 9 of transparent organic plastic sample 8, beam splitting system 2, computer control system 5 and be controlled by computer control system
Laser 1, focusing system 3, the optical beam scanning system 4 of system 5, computer control system 5 pass through integrated data line 7 and laser
1st, focusing system 3, optical beam scanning system 4 couple, and realization is synchronous with optical beam scanning system 4 to laser 1, focusing system 3, and

Face is coated with the reflectance coating of optical maser wavelength, and the reflectivity of the reflectance coating is preferably 50%, and the preceding surface of the second prism 24 is coated with sharp
The film that is all-trans of optical wavelength.
Focusing system is generally made up of in conventional design the optical lens of more than three, or by Zoom lens (or
Speculum) composition, it is possible to achieve the control to laser beam focus condition and focus position.

Penetrate mirror galvanometer 42, F-theta mirrors 43 and servo controlling card 44；F-theta mirrors by heavy caliber, wide range scanning focus lens group
Into uniform focus point can be formed in the plane of scanning motion.Optical beam scanning system can be realized to incident beam in X, Y-axis two
Aspect is scanned with larger angle, and still good focusing can be kept in same plane when scanning angle is very big,
Therefore gross distortion will not occur for the size and dimension of focal beam spot.
The process that the device that the utility model is provided carries out interior carving is as follows：The output wavelength of laser 1 is 1.9 microns~2.1
After the laser of micron, the collimated system collimation of the laser beam of output, then after the first prism 23 and the second prism 24 it is divided into two
The equal beamlet of beam power, one of beamlet is reflected downwards, and another beamlet passes through the second prism 24
Afterwards, also it is reflected downwards, the direction of propagation of this two beams laser is identical and parallel, but apart has certain interval, light beam
Between do not have overlap part.By beam splitting system 2 spread out of Lai two beam laser sequentially enter again focusing system 3 and light beam scanning
System 4, realizes the control to laser beam focus condition and focus position, uniform focus point is formed in the plane of scanning motion.Two beams
The specified location that laser beam is finally converged and focused on transparent organic plastic sample 8.Laser beam will be minimum near focus point
In the range of organic plastics be warmed to its glass transition point, start melt.At this moment turn off laser or incited somebody to action by optical beam scanning system 4
Light beam is moved to next position.The organic plastics of the specified location starts cooling, because the organic plastics around focus point does not have
Have and reach glass transition point, will not melt, therefore due to stress, crystallization direction of the organic plastics of regelation etc. is micro-
The organic plastics that structure is different from surrounding is seen, causes the difference of its refractive index, the effect of interior carving is produced.
Phase transition process inside organic plastics is as shown in Figure 4.Starting stage, laser is opened, and the temperature of plastics inner is rapid
Rise, transparent plastic is heated at laser spot, start to melt, when transparent plastic has reached glass transition point, turn off laser,
The temperature of plastics inner is begun to decline, and gradually decreases to room temperature, and transparent plastic solidifies again, produces the refractive index as caused by stress
Change point, forms interior carving effect.
