Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of optoelectronics, and in particular relates to a crystal clamping constant temperature device and a crystal clamping constant temperature system. Background Art
[0002] As one of the core components of the laser, the optical crystal needs to maintain a relatively stable working state. In the actual working process of the optical crystal, it is particularly important to maintain the temperature of the optical crystal. If there is a problem with the working temperature of the optical crystal, it will directly affect the output power of the laser and cause the deterioration of the roundness of the laser spot, such as forming an elliptical or worse spot shape. Based on this, in the actual use of the optical crystal, it is necessary to clamp the optical crystal through a constant temperature component, and then use the constant temperature component to maintain a stable working temperature of the optical crystal. Therefore, it is particularly important to ensure good contact between the optical crystal and the heat sink.
[0003] In the related art, two symmetrically arranged thermostatic components are usually used to clamp the optical crystal between the two thermostatic components, and then through-hole screws are matched with corresponding bolt holes on the thermostatic components to fix the two thermostatic components together. However, due to certain processing errors in the dimensions of the optical crystal and the thermostatic components, a certain gap is generated between the side of the optical crystal and the contact surface of the thermostatic component, which in turn affects the thermal conductivity. In addition, since the related art uses screw fixing to fix the optical crystal, it is inevitable that the optical crystal will generate a large clamping stress, which may even cause the optical crystal to break during actual operation. At the same time, for nonlinear frequency doubling crystals, the phase matching conditions will be destroyed, resulting in a decrease in the nonlinear conversion rate. Utility Model Content

[0033] Specifically, if Figure 1 and Figure 2 As shown in , in a preferred embodiment of the present application, the crystal holding thermostat holds an optical crystal 2 extending along a first direction. Accordingly, the crystal holding thermostat comprises a thermostat component 1 and a clamping component. A thermostat extending along the first direction is provided on the thermostat component 1. At the same time, both ends of the thermostat along the first direction pass through the thermostat component 1. Furthermore, the opening of the thermostat is provided on the side wall of the thermostat component 1, so that the optical crystal 2 can be stably installed in the thermostat through the notch provided on the thermostat component 1. At the same time, in order to ensure that the thermostat component 1 stably controls the temperature of the optical crystal 2, part of the side wall of the optical crystal 2 contacts the inner wall of the thermostat, thereby enabling a stable heat exchange to be formed between the optical crystal 2 and the inner wall of the thermostat until the heat is transferred to the outer wall of the thermostat component 1. This allows the thermostat component 1 to stabilize the temperature of the optical crystal 2 while providing stable fixation for the optical crystal 2.
[0034] Furthermore, the clamping member includes a fixing assembly and at least one elastic binding member 11. The fixing assembly is disposed within the notch, and the sidewall surface of the fixing assembly facing the optical crystal 2 abuts at least partially against the sidewall surface of the optical crystal 2. This allows the optical crystal 2 to be stably fixed under the clamping action of the fixing assembly and the thermostatic bath. To achieve elastic clamping of the optical crystal 2, each elastic binding member 11 is sleeved on the sidewall surfaces of the fixing assembly and the thermostatic member 1. This allows the fixing assembly and the thermostatic member 1 to stably clamp the optical crystal 2 while also preventing the optical crystal 2 from breaking due to excessive clamping stress.
[0035] Furthermore, in a preferred embodiment of the present application, the optical crystal 2 is a rectangular parallelepiped structure, and the thermostatic bath is a corresponding rectangular parallelepiped structure. The optical crystal 2 is embedded in the thermostatic bath, and the fixing assembly is embedded in the notch of the thermostatic bath. The sidewalls of the fixing assembly abut against the sidewalls of the optical crystal 2. A plurality of elastic restraints 11, mounted on the outer walls of the thermostatic member 1 and the fixing assembly, ensure sufficient contact between the optical crystal 2 and the abutting surface of the thermostatic bath.
[0036] It is worth noting that, in the preferred embodiment of the present application, the length extension direction of the optical crystal 2 is the first direction; in the horizontal plane, the width direction of the optical crystal 2 is the second direction; in the vertical plane, the height direction of the optical crystal 2 is the third direction.

In actual use, the optical crystal 2 is embedded in the semicircular thermostatic bath, and the fixing assembly is buckled onto the optical crystal 2. The fixing assembly is elastically limited by a plurality of elastic restraints 11, thereby achieving a stable fixation between the optical crystal 2 and the thermostatic bath.
[0038] Further preferably, in a preferred embodiment of the present application, the clamping member includes at least two elastic binding members 11, and each elastic binding member 11 is spaced apart along the first direction on the side wall surface of the constant temperature member 1 and the side wall surface of the fixed component to ensure that the elastic binding member 11 uniformly applies the fastening force to the fixed component, thereby improving the stability of the fixation of the optical crystal 2.
[0039] In more detail, in a preferred embodiment of the present application, in order to facilitate the accuracy of the elastic binding member 11 in limiting the position between the fixed component and the constant temperature component 1, a first limiting groove 7 is provided on the outer wall surface of the constant temperature component 1 at the position corresponding to each elastic binding member 11. Accordingly, part of the elastic binding member 11 is embedded in the first limiting groove 7, and the remaining part of the elastic binding member 11 is directly tied to the side wall surface of the fixed component facing away from the optical crystal 2, so that the elastic binding member 11 can be conveniently mounted on the outer wall surface of the constant temperature component 1.
[0040] Furthermore, in a preferred embodiment of the present application, a second limiting groove 8 corresponding to the elastic binding member 11 is also provided on the side wall surface of the fixing component facing away from the optical crystal 2. Part of the elastic binding member 11 is embedded in the second limiting groove 8, and the remaining part of the elastic binding member 11 is directly tied to the outer wall surface of the constant temperature component 1, so that the elastic binding member 11 can be conveniently mounted on the outer wall surface of the fixing component.
[0041] Further preferably, in a preferred embodiment of the present application, a first limiting groove 7 corresponding to the elastic binding member 11 is provided on the outer wall surface of the thermostatic component 1. Correspondingly, a second limiting groove 8 corresponding to the elastic binding member 11 is provided on the side wall surface of the fixing assembly facing away from the optical crystal 2. During actual use, the elastic binding member 11 is sequentially inserted into the first limiting groove 7 and the second limiting groove 8, which not only facilitates the fixing of the elastic binding member 11 but also ensures that the elastic binding member 11 can provide a reliable elastic clamping force for the fixing assembly and the thermostatic component 1 to clamp the optical crystal 2.
[0042] In more detail, in a specific preferred embodiment of the present application, at least one first limiting groove 7 is provided on the side wall surface of the constant temperature component 1 at its end position close to the first direction, and correspondingly, at least one second limiting groove 8 is provided on the side wall surface of the fixing component at its end position close to the first direction, that is, at least one elastic binding member 11 is provided on the side wall surface close to both ends of the crystal clamping constant temperature device, and the elastic binding member 11 is respectively embedded in the corresponding first limiting groove 7 and second limiting groove 8. Preferably, the elastic binding members 11 arranged at both ends are symmetrically arranged, thereby ensuring the uniformity of the elastic stress distribution borne by the optical crystal 2.
[0043] Furthermore, in a preferred embodiment of the present application, the elastic binding member 11 includes an elastic band. Of course, the elastic binding member 11 may also include both an elastic band and an elastic steel wire rope. Specifically, the elastic band abuts the bottoms of the first limiting groove 7 and the second limiting groove 8, respectively, providing an elastic clamping force for the fixing assembly and the thermostatic component 1 to elastically clamp the optical crystal 2. At the same time, the elastic steel wire rope is also embedded in the first limiting groove 7 and the second limiting groove 8, and the elastic steel wire rope is spaced a certain distance from the bottoms of the first limiting groove 7 and the second limiting groove 8, so as to maintain the thermostatic component 1 and the fixing assembly clamping the optical crystal 2 after the elastic band fails.
[0044] Further preferably, in another preferred embodiment of the present application, the elastic binding member 11 can also be an elastic ring-shaped steel wire with a notch. During actual use, the elastic binding member 11 is embedded in the first limiting groove 7 and the second limiting groove 8 at the same time, and at the same time, the deformation elasticity of the ring-shaped steel wire is used to provide an elastic clamping force for the optical crystal 2.
[0045] In more detail, in a specific preferred embodiment of the present application, the crystal clamping constant temperature device is a cylindrical structure as a whole. Accordingly, the first limiting groove 7 and the second limiting groove 8 both have arc-shaped groove bodies, and the elastic binding member 11 also adopts an annular structure.
[0046] Furthermore, in a preferred embodiment of the present application, the fixing assembly includes a fixing plate 4 and a pressing plate 3, wherein the pressing plate 3 is disposed within the thermostatic bath, between the optical crystal 2 and the fixing plate 4. The fixing plate 4 is partially embedded within the thermostatic bath, and a second limiting groove 8 corresponding to the elastic restraint 11 is disposed on the sidewall of the fixing plate 4 facing away from the optical crystal 2.
[0047] Further preferably, in a preferred embodiment of the present application, the fixing assembly further includes at least one pressing rod and a corresponding pressing rod extending through a pressing hole 6 on the fixing plate 4. The pressing rod is embedded in the pressing hole 6, and the end of the pressing rod facing the optical crystal 2 can abut against the pressing plate 3, thereby enabling the pressing rod to transmit the elastic force of the elastic binding member 11 to the pressing plate 3, thereby facilitating elastic clamping of the optical crystal 2. Preferably, two pressing holes 6 are arranged on the fixing plate 4 at intervals along the first direction.
[0048] In more detail, in a preferred embodiment of the present application, an interference fit is formed between the outer wall surface of the clamping rod and the inner wall surface of the clamping through hole 6, so that the clamping rod can controllably adjust the position of the end of the clamping rod toward the optical crystal 2 relative to the clamping through hole 6. In actual use, if a larger elastic clamping force is required between the optical crystal 2 and the thermostatic bath, the length of the end of the clamping rod toward the optical crystal 2 can be extended, thereby increasing the relative distance between the fixing plate 4 and the thermostatic bath, so that the deformation length of the elastic binding member 11 is longer, thereby increasing the elastic clamping force between the optical crystal 2 and the thermostatic bath. If the elastic clamping force between the optical crystal 2 and the thermostatic bath needs to be reduced, the length of the end of the clamping rod toward the optical crystal 2 can be shortened, thereby shortening the relative distance between the fixing plate 4 and the thermostatic bath, thereby shortening the deformation length of the elastic binding member 11, thereby reducing the elastic clamping force between the optical crystal 2 and the thermostatic bath.
[0049] Furthermore, in another preferred embodiment of the present application, a threaded structure is provided between the outer wall surface of the clamping rod and the clamping through hole 6, that is, the clamping rod and the clamping through hole 6 are threadedly matched to facilitate flexible adjustment of the extension length of the clamping rod toward the protruding end of the optical crystal 2.
[0050] Further preferably, in the preferred embodiment of the present application, a limiting pit 5 is provided on the pressing plate 3 at a position corresponding to the pressing rod, so that the end of the pressing rod facing the optical crystal 2 can always be embedded in the limiting pit 5, thereby ensuring the accuracy of the relative position of the pressing rod during the position adjustment of the extended end of the pressing rod.
[0051] More specifically, in a preferred embodiment of the present application, a first mounting groove 9 and a second mounting groove 10 of increasing widths are provided at the notch of the thermostatic bath, wherein the pressing plate 3 is disposed in the first mounting groove 9, and the fixing plate 4 is disposed in the second mounting groove 10.

[0052] Further preferably, in another preferred embodiment of the present application, a crystal clamping constant temperature system is disclosed, which includes the above-mentioned crystal clamping constant temperature device.
[0053] Furthermore, in another preferred embodiment of the present application, the crystal clamping constant temperature system also includes a thermistor, a heating resistance wire, a heating column and a fixed base. The crystal clamping constant temperature device, the furnace core heating column and the fixed base are fixedly connected in sequence, and the thermistor wire is wound around the heating column.
[0054] The crystal clamping constant temperature device and crystal clamping constant temperature system of the present invention have a simple structure, stable operation, and convenient use. They are formed by providing a constant temperature bath for accommodating the optical crystal 2 on the constant temperature component 1 and a fixing component provided on the notch of the constant temperature bath, thereby forming a clamping form for the optical crystal 2.

At the same time, a plurality of first limiting grooves 7 and second limiting grooves 8 provided on the outer wall of the constant temperature component 1 and the side wall of the fixing plate 4 facing away from the optical crystal 2 can effectively improve the convenience of the elastic binding member 11 being installed and tied. By setting the first limiting groove 7 and the second limiting groove 8 near the first direction end of the crystal supporting constant temperature device, the elastic binding member 11 can evenly transmit the elastic force to the contact surface between the optical crystal 2 and the constant temperature bath, which has good application value and promotion prospects.
