Description
Technical Field
The invention relates to a laser resonant cavity, in particular to a method and a device for fixing a cavity mirror of the laser resonant cavity by using viscose.
Background
A laser resonator is an essential component of a laser and is generally composed of mirrors (also called cavity mirrors) arranged at both ends of an active medium perpendicularly to the axis of the active medium. The light waves are reflected back and forth in the laser cavity to provide positive feedback of the light energy, and the laser cavity is also capable of controlling the characteristics of the oscillating beam within the cavity. One of the cavity mirrors at each end of the laser resonator is a partially transmissive mirror to direct the laser light out of the cavity.
In laser research such as solid-state lasers, accurate adjustment and fixation of the mirror of the cavity mirror of the laser resonator is an important factor for obtaining high-efficiency and high-quality laser output. Normally, the cavity mirror lens is mounted directly in the optical adjustment frame, so that the lens can be directly adjusted and fixed with high precision. Although the method has simple structure and high adjustment precision, the optical adjusting frame can be aged after long-term use, and the position of the lens is deviated, thereby causing the quality of the laser beam output by the laser to be reduced. In addition, the optical trim frame is large and cannot generally be installed in a compact laser.
Therefore, there is a need for improvements in existing apparatus and methods for securing cavity mirrors of laser resonators.

Detailed Description
Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the drawings are only for purposes of illustrating the invention and are not to be construed as limiting the invention.
Fig. 1 schematically shows a schematic side view of a cavity mirror for fixing a laser resonator by means of an arrangement for fixing a cavity mirror for a laser resonator according to the invention with adhesive, fig. 2 schematically shows a schematic top view of a cavity mirror for fixing a laser resonator by means of an arrangement for fixing a cavity mirror for a laser resonator according to the invention with adhesive, and fig. 3 schematically shows an exploded view of the cavity mirror and adjustment module of the laser resonator of fig. 1 and 2. As shown in fig. 1-3, the device for fixing the cavity mirror of a laser resonator by using adhesive according to the present invention comprises a lens adjusting module 1 and a light path indicating module 3.
The lens adjusting module 1 includes a holding cylinder 5 for detachably fixing and holding a lens and an adjusting bracket 7 for adjustably supporting the holding cylinder 5. The holding cylinder 5 has a cylindrical shape, and the lens can be fixed to one end (for example, the tip) of the holding cylinder 5 by ultraviolet glue. In addition, the inner diameter of the holding cylinder 5 may be slightly larger than the outer diameter of the lens, and a notch may be formed at the end of the holding cylinder 5 for mounting the lens. In this way, the lens can be fixed in the holding cylinder 5 by means of screws and the place to be contacted with the fixing platform is exposed through the gap. The adjustment bracket 7 comprises a main body part 9 and a plurality of adjustment knobs 11 connected to the main body part by means of an operating mechanism not shown. The holding cylinder 5 is fixedly connected at the other end (e.g., the rear end) to the main body portion 9 of the adjustment bracket 7. By operating the adjustment knob 11 in this way, the positions of the main body 9 and the holding cylinder 5 can be adjusted, and the position of the lens held by the holding cylinder 5 can be adjusted.
The light path indicating module 3 includes an indicating light source 13 and an aperture 15 that can be disposed in front of the indicating light source 13. The instruction light source 13 is for emitting a laser beam forming a reference optical path toward the aperture stop 15.
The method of fixing the cavity mirror of the laser resonator with adhesive according to the present invention will be described in detail below with reference to fig. 1 to 3 and fig. 4.
At block S1, the mirror plate 17 of the cavity mirror of the laser resonator is fixed to the front end of the holding cylinder 5 of the mirror adjustment module 1 by ultraviolet glue or screws or the like, and then the holding cylinder 5 to which the mirror plate 17 is fixed is fixedly attached to the main body portion 9 of the adjustment frame 7 of the mirror adjustment module 1. The position of the adjusting frame 7 is fixed so that the lens 17 fixed to the holding cylinder 5 is located upright on a fixing platform 19 to be used for fixing the lens 17, according to the relation of the adjusting frame 7 and the light passing direction of the lens 17. The fixed platform 19 may be part of the laser housing. Of course, it is also possible to fix the holding cylinder 5 to the main body 9 of the adjustment frame 7 first and then fix the lens 17 to the holding cylinder 5.
At block S2, the pointing light source 13 on the other side of the fixed platform 19 is turned on, causing the pointing light source 13 to emit a laser beam toward the aperture stop 15. The aperture stop 15 is adjusted so that the laser beam emitted by the indicating light source 13 and passing through the aperture stop 15 is incident on the mirror 17 to form a reference optical path, and the aperture stop 15 is fixed so as to fix the position of the reference optical path R.
At block S3, the adjustment knob 11 of the adjustment frame 7 of the mirror adjustment module 1 is operated to effect position adjustment of the mirror 17 by positional change of the main body portion 9 and the holding cylinder 5 so that the reflected light path formed by the laser beam reflected by the mirror 17 returns along the reference light path R. The mirror adjustment module 1 is a multi-azimuth adjustment device that can make a plurality of azimuth adjustments, such as rotation, pitch, up-down and/or side-to-side adjustments, to the position of the mirror 17 to adjust the mirror 17 to a proper position, i.e., to allow the reflected light path formed by the laser beam reflected by the mirror 17 to return along the reference light path R.
At block S4, an ultraviolet glue is applied to secure the lens 17 to the securing platform 19 for securing the lens 17. Although the lens 17 may be secured directly to the mounting platform 19, a ceramic pad 21 may be provided on the mounting platform 19 to improve the stability of the lens 17 when mounted to the mounting platform 19. In this case, the ceramic liner 21 is fixed to the fixing platform 19 by means of the first layer of uv-glue 23, and then the lens 17 is fixed to the ceramic liner 21 by means of the second layer of uv-glue 25.
At block S5, after the uv glue used to secure the lens 17 to the mounting platform 19 is cured, the uv glue used to secure the lens 17 to the retention cartridge 5 is removed or the screws used to secure the lens 17 to the retention cartridge 5 are loosened, and the entire lens adjustment module 1 is then removed. In this way, the fixing of the lens 17 to the fixed platform 19 is completed.
Curing stress generated during curing of the ultraviolet glue used for fixing the mirror 17 to the fixing platform 19 may cause a deviation in the position of the mirror 17, and thus a change in the reflected light path, so that the reflected light path formed by the laser beam reflected by the mirror 17 is shifted with respect to the reference light path R. To this end, the method of fixing the cavity mirror of the laser resonator with adhesive according to the present invention may further include a process of detaching the mirror and re-installing the mirror in consideration of compensation for the curing stress of the ultraviolet adhesive. This process is described below to eliminate positional deviation of the lens 17 due to curing stress of the ultraviolet glue.
At block S6, a mirror position error caused by the uv glue curing stress is determined by marking a deviation position of the reflected light path DR reflected and shifted by the mirror 17 from the reference light path R at the aperture stop 15. The magnitude of the deviation position of the reflected light path DR from the reference light path R is represented by an angle α.
At block S7, the reflected light path position after compensation for the uv gel curing stress and before uv gel curing is considered is marked on the aperture stop 15 according to the lens position error determined at block S6. When the deviation position of the reflection light path DR with respect to the reference light path R is an angle α, the reflection light path position of the mark, which is considered after the compensation of the ultraviolet glue curing stress and before the ultraviolet glue curing, is located at a position on the aperture stop 15 where the angle α is formed between the reference light path R and the mark in the radial opposite direction, that is, at a position on the aperture stop 15 symmetrical to the deviation position of the reflection light path DR of the mark with the reference light path R as the center.
At block S8, the uv gel used to secure the lens 17 to the mounting platform 19 is removed and S1 is repeated.
At block S9, the adjusting knob 11 of the adjusting carriage 7 of the mirror adjusting module 1 is operated again so that the reflected light path formed by the laser beam reflected by the mirror 17 coincides with the reflected light path position marked on the aperture stop 15 after the compensation of the curing stress is considered at S7.
At block S10, uv glue is again applied to secure the lens 17 to the securing platform 19 for securing the lens 17. In order to avoid the influence of the application of the uv glue on the position of the lens, the uv glue is applied as much as possible at the same angle and the same amount each time.
At block S11, after the uv glue applied at S10 is cured, the entire lens adjustment module 1 is again removed.
In order to avoid the error introduced by measuring the offset position angle α and to more accurately eliminate the position offset of the lens caused by the curing stress generated during the curing process of the ultraviolet glue, the following blocks S7 ', S8 ' and S9 ' may be used instead of the above-described blocks S7, S8 and S9.
At block S7', the uv glue used to secure lens 17 to mounting platform 19 is removed and block S1 is repeated.
At block S8', the adjustment knob 11 of the adjustment frame 7 of the lens adjustment module 1 is operated so that the reflected light path reflected by the lens 17 coincides with the previously marked offset position, and further the adjustment knob 11 of the adjustment frame 7 of the lens adjustment module 1 is operated so that the reflected light path reflected by the lens 17 returns along the reference light path R.
Typically, the adjustment knob 11 of the adjustment bracket 7 is a knob with an angular scale. At block S9 ', the adjusting knobs 11 of the adjusting frame 7 of the lens adjusting module 1 are continuously operated such that the respective adjusting knobs 11 are rotated continuously in the same direction by the same angle as the block S8' for adjusting the reflected light path from the marked deviated position to return along the reference light path R, so as to adjust the reflected light path to the reflected light path position after the compensation of the uv-gel curing stress and before the uv-gel curing is considered.
Through the additional operations, the position deviation of the lens caused by the curing stress generated in the curing process of the ultraviolet glue used for fixing the lens on the fixed platform can be eliminated, and the coincidence of the reflected light path and the reference light path after the ultraviolet glue is cured is ensured, so that the accuracy of the cavity mirror lens for fixedly mounting the laser resonant cavity is further improved.
According to the method and the device for fixing the cavity mirror of the laser resonant cavity by using the adhesive, the position deviation of the lens caused by the aging of the optical adjusting frame can be prevented by avoiding the optical adjusting frame, so that the quality of the laser beam output by the laser is ensured, and the stability of the laser in long-time working is improved. In addition, because an optical adjusting frame is not needed, the space required by the lens is reduced, and the fixing of the cavity mirror lens of the laser resonant cavity in the compact laser is particularly facilitated.
While the invention has been described in detail in connection with the preferred embodiments thereof, it is to be understood that such detail is solely for that purpose and that no limitation of the invention is thereby intended. For example, the UV glue used in the preferred embodiment is one that is curable by UV light irradiation, but other glues such as room temperature, medium temperature or high temperature curing can be used. The scope of the invention is determined by the claims.
