Abstract

The invention provides a surface processing method of a strip laser medium. According to the method, high surface figure accuracy and excellent surface smoothness can be obtained by the strip laser medium at the same time. The surface processing method of the strip laser medium comprises the following steps of: bonding and hanging the cut strip laser medium by a binder; respectively grinding and pre-polishing two large surfaces on a plane grinder; hanging the pre-polished strip laser medium in an elastic adsorption manner, and precisely polishing the strip laser medium after being hung in the elastic adsorption manner on the plane grinder by a synthesis polishing plate. By adopting the surface processing method of the strip laser medium provided by the invention, hanging in the elastic adsorption manner is adopted by precisely finishing; the operation is simple and convenient; a problem of surface deformation after a element is taken off is not caused; glass or crystal for tripping does not need to be adhered around the work-piece, and a risk of edge breakage or angle breakage of the element in a processing process is avoided.

Description

technical field

[0001] The invention relates to the technical field of optical processing, in particular to a method for processing the surface of a slab laser medium. Background technique

[0002] With its high peak power and compact structure, solid-state lasers with high average power are used in civilian applications (such as laser cutting, welding, heat treatment, marking), military applications (such as laser radar, ranging, photoelectric countermeasures) and space communications. important application prospects. Because the traditional solid-state laser uses a rod-shaped laser working medium, the thermal lens effect is very serious, which limits the laser output power and beam quality. The use of slab-shaped laser media can effectively improve this situation. By designing a reasonable zigzag optical path, the influence of thermal lens effect on the output laser can be significantly reduced, and the birefringence effect caused by stress can be eliminated. In order to...
