Most of the existing solid laser manufacturers wrap frequency doubling and sum frequency crystals with indium sheets, and because the indium sheets are soft in texture, the problem of slight deviation of the crystals caused by long-time deformation is easily caused after the crystals are wrapped and clamped, the conversion efficiency is reduced to a certain extent after the crystals are deviated, and the performance change of the whole laser is further influenced. In the aspects of adjustment and stability of a frequency doubling structure, the crystal size is precise, so the processing precision of the structure is generally required to be high, the cost is high, and the problem of deformation in the long-term use process is also caused by poor design and material selection; some rigid clamping designs are also prone to stress cracking of the fragile crystal due to insufficient tolerance control. Based on the basis, the clamping device, the double-crystal clamping device and the debugging system are provided to solve the problem of the existing clamping structure.

The utility model discloses an aspect of the embodiment provides a clamping device, include: the deformation part 150, the bearing seat and the crystal cover 110; the crystal cover 110 is covered on the bearing seat and a clamping cavity is formed between the crystal cover 110 and the bearing seat, the clamping cavity is used for accommodating the crystal 300 to be clamped, and the deformation part 150 is located in the clamping cavity and is attached to the crystal 300 to be clamped, so that the crystal cover 110 is matched with the bearing seat to clamp the deformation part 150 and the crystal 300 to be clamped.

In an example, the crystal to be clamped can be clamped and fixed by the clamping device, so that subsequent operations such as debugging and the like of the crystal 300 to be clamped are realized. As shown in fig. 1 and 2, the clamping device includes a bearing seat for bearing, and the crystal cover 110 may be connected to the bearing seat in a covering manner, where the connection manner may be detachable, such as a screw connection as shown in fig. 1, or may be other connection manners such as a snap connection. Meanwhile, after the two are connected, a clamping cavity is formed between the two, and the clamping cavity can be used for accommodating the crystal 300 to be clamped. In order to avoid excessive stress on the crystal 300 to be clamped, the deformation piece 150 can be arranged in the clamping cavity, clamping force is gradually generated on the crystal 300 to be clamped and the deformation piece 150 in the process that the crystal cover 110 and the bearing seat are gradually connected in place so as to conveniently and conveniently fix and subsequently debug the crystal 300 to be clamped, in the fixing process, the clamping force on the crystal cover 110 and the bearing seat on the crystal 300 to be clamped is reduced through the deformation of the deformation piece 150 (namely, the deformation piece 150 is at least arranged in the direction that the crystal cover 110 and the bearing seat are close to each other for clamping), so that the crystal 300 to be clamped can be effectively clamped and fixed, and meanwhile, the phenomenon that the crystal 300 to be clamped is broken due to factors such as tolerance of the clamping piece can be avoided.

During actual clamping, the bearing seat can be fixed, then the crystal 300 to be clamped and the deformation piece 150 are preset at the position where the clamping cavity is to be formed, then the crystal cover 110 gradually approaches the bearing seat, in the approach process, the crystal cover 110 is gradually changed from contacting the deformation piece 150 or the crystal 300 to be clamped into matching with the bearing seat to generate clamping force on the deformation piece 150 and the crystal 300 to be clamped, due to tolerance factors, when the clamping force of the crystal cover 110 and the bearing seat is too large, the clamping force of the crystal 300 to be clamped can be relieved by the deformation piece 150, and therefore the phenomenon of damage of the crystal cover 110 and the bearing seat is avoided; when the clamping force between the crystal cover 110 and the bearing seat is too small, the thickness of the deformation part 150 is used for absorbing tolerance, so that the clamping force between the crystal cover 110 and the bearing seat to the crystal 300 to be clamped is increased, and the crystal cover and the bearing seat can be stably clamped. Tolerance generated between the clamping pieces can be absorbed through the deformation characteristic of the deformation piece 150, the integrity of the crystal 300 to be clamped is effectively improved when the crystal is clamped, meanwhile, the manufacturing requirement on the clamping device can be effectively reduced, and the manufacturing cost is reduced. Meanwhile, because the tolerance of the crystal 300 to be clamped is generally large and generally one millimeter of positive and negative zero points, the clamping device in the embodiment of the application can meet the requirements of various crystals by only selecting the appropriate thickness of the deformation part 150, and the condition that the tolerance and the size of the structure are frequently required to be adjusted according to the actual size of the crystal 300 to be clamped in the conventional unreasonable structural design is avoided.

As shown in fig. 2, the crystal 300 to be clamped may be a frequency doubling crystal 320, a frequency tripling crystal 310, or the like; when the crystal 300 to be clamped is in a stable clamping state, one side of the deformation element 150 is in contact with the surface of the crystal 300 to be clamped, and the other side of the deformation element may be in contact with only the sidewall 123 of the clamping cavity formed by the crystal cover 110, or in contact with only the sidewall 123 of the clamping cavity formed by the bearing seat, or in contact with both the sidewall 123 of the clamping cavity formed by the crystal cover 110 and the sidewall 123 of the clamping cavity formed by the bearing seat. This embodiment does not do all to it and does not do the restriction, as long as when treating clamping crystal 300 at crystal lid 110 with the bearing seat clamping, can alleviate the clamping-force of treating clamping crystal 300 through deformation piece 150 and avoid its excessive atress damaged can.

Optionally, a plurality of bending portions are disposed on the deformation element 150, and the plurality of bending portions are sequentially disposed along the extending direction of the crystal 300 to be clamped.

For example, in order to further improve the deformation capability of the deformable member 150, a plurality of bent portions may be further disposed on the deformable member 150, that is, the deformable member 150 is formed by bending a plurality of times. The plurality of bending parts are sequentially arranged along the extending direction of the crystal 300 to be clamped, so that the whole crystal 300 to be clamped can be well protected by the deformation part 150 comprehensively. For example, as shown in fig. 2, when the crystal 300 to be clamped is a prism, the plurality of bending portions are sequentially arranged along the length direction thereof. The plurality of bent portions may include two bent portions, three bent portions, four bent portions, and the like, and the plurality of bent portions may be intermittently disposed therebetween or may be continuously disposed as shown in fig. 2.

As shown in fig. 1 and fig. 2, when the clamping cavity has openings at two ends of the prism to-be-clamped crystal 300 along the length direction, the bent deformation member 150 can be located in the clamping cavity, and after the bent portion is deformed, the stretching direction of the bent portion can also be along the length direction of the to-be-clamped crystal 300, so as to avoid interference on the to-be-clamped crystal 300 after the bent portion is pressed, deformed and extended. The deformable member 150 may be a sheet of metal sheet material such as copper.

For example, in order to maintain the temperature of the crystal 300 to be clamped within a suitable range after being clamped by the clamping device, so that the crystal can maintain better performance, a temperature control device may be correspondingly provided. In order to stably clamp the temperature control device to achieve stable temperature adjustment, the carrier may further include a crystal seat 120 and an adjusting part 130, one side of the crystal seat 120 cooperates with the crystal cover 110 to complete clamping of the crystal 300 to be clamped, that is, one side wall 123 of the crystal seat 120 may cooperate with the crystal cover 110 to form a clamping cavity in the foregoing embodiment, and meanwhile, the deformation part 150 may also be located in the clamping cavity; the other side of the crystal holder 120 can cooperate with the adjusting member 130 to clamp the temperature control device therebetween. As shown in fig. 3, in order to improve the stability of clamping, a groove may be disposed on one side of the adjusting element 130 close to the crystal seat 120, or a groove may be disposed on one side of the crystal seat 120 close to the adjusting element 130, and the two grooves may be adapted to receive and clamp the temperature control device. The temperature control device can control the temperature of the crystal 300 to be clamped through the crystal seat 120, and therefore the temperature control device can be attached to the crystal seat 120, so that the temperature control device and the crystal seat can perform good heat transmission conveniently. In addition, the crystal holder 120 and the crystal cover 110 may be made of a material with good thermal conductivity, such as red copper. Correspondingly, the adjusting member 130 may be made of aluminum material for the whole clamping device to have the characteristics of good strength, small deformation and light weight.

The connection mode between the controller and the temperature sensor and the temperature regulator 140 may be wired or wireless, and when the connection mode is wireless, signal transceiver modules capable of communicating with each other, such as a wireless communication module, a bluetooth module, etc., should be respectively integrated on the temperature sensor, the temperature regulator 140 and the controller.

Specifically, when the collected temperature information is smaller than the preset temperature range, the controller controls the temperature regulator 140 to heat; when the collected temperature information is greater than the preset temperature range, the controller controls the temperature regulator 140 to refrigerate.

Illustratively, as shown in fig. 3, the crystal cover 110 may be an L-shaped structure formed by connecting a cover 112 and a wall 113. A through groove is formed in the crystal seat 120, an L-shaped structure is formed by the bottom wall 122 and the side wall 123 of the through groove, and the L-shaped structure of the crystal cover 110 and the L-shaped structure of the crystal seat 120 are mutually butted to form a hollow space with a clamping cavity. As shown in fig. 4, in order to make the crystal cover 110 and the crystal holder 120 completely fit when the crystal is clamped, a gap may be formed between the retaining wall 113 and the side wall 123 of the through groove, that is, a small gap, that is, a notch may be formed, so that the tolerance fit relationship between the crystal cover 110 and the crystal holder 120 may be reduced, and the manufacturing costs of the two may be reduced.

The laser output from the reflection and refraction side surface of the frequency tripling inclined surface can be transmitted through the inclined surface 111, and the risks of temperature increase and runaway caused by the fact that the laser is irradiated inside the structure of the clamping device are prevented. The setting requirement of the inclined angle of the inclined plane 111 can be reasonably set according to the emergent direction of the laser after reflection and refraction, so that the part of laser does not return to the clamping device.
