Embodiment Construction

[0045] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0046] It can be seen from the application product index of the laser crystal itself that the azimuth angle of the optical axis given by the crystal processing technology is generally ±0.5°. From this, it can be seen that the crystal should be fine-tuned for its optical axis during use; the fine-tuned amount of the angle can reach ±30' can meet the requirements.

[0047] Specifically, in the laser crystal assembly posture, the adjustments to be made include:

[0048] 1. The axial displacement adjustment of the crystal group is generally completed by its front group and the front reflectio...

Abstract

The invention provides a crystal base group device with a fine-adjustable two-dimensional angle. The crystal base group device comprises the components of a crystal set base, a fixing board, an elastic adjusting screw set, a crystal set, a first fastening screw set, a first central positioning pin and a second central positioning pin. The crystal set base is reversed T-shaped. One end of the fixing board is fixed on a vertical plate, and the other end is provided with the elastic adjusting screw set. The elastic adjusting screw set abuts against the top of the crystal set. The bottom of the crystal set is a projected cylindrical surface. The cylindrical surface of the crystal set abuts against the cylindrical surface of the base. Fine adjustment can be performed on the two-dimensional angle of the crystal base group device in the horizontal surface and the vertical surface. Convenient-operation elastic continuous fine adjustment can be performed in adjustment, and furthermore rigid locking after fine adjustment can be performed. A reliable multidirectional angle fine adjustment function is realized through a simple structure, thereby preventing common tedious design, effectively reducing central height, realizing small structure design, and effectively realizing high stability of the structure.

Description

【Technical field】 [0001] The invention relates to the technical field of lasers, in particular to a crystal seat group device capable of finely adjusting two-dimensional angles. 【Background technique】 [0002] During the assembly and adjustment process of laser products, the adjustment of laser crystals is an important link. In order to achieve a good light output effect, it is often necessary to fine-tune the spatial posture of the laser crystals. [0003] Commonly used laser crystals mainly include neodymium-doped yttrium vanadate (Nd: YVO4) crystals and neodymium-doped yttrium aluminum garnet (Nd: YAG) crystals, which are widely used in the laser industry. Laser crystals are a very important basic device . [0004] One of the main structural forms of laser crystals is a cuboid shape, such as 3×3×16.5 Nd:YVO4 yttrium vanadate crystals. [0005] For the clamping and debugging of laser crystals in lasers, the current problems that generally need to be solved are: [0006]...
