Embodiment Construction

[0018] The present invention proposes a kind of method that adopts Brewster angle processing Nd:YAG laser crystal, carries out according to following steps:

[0019] Step 1, material selection of crystal

[0020] The selection of materials adopts He-Ne laser irradiation to irradiate visible scattering points with the naked eye;

[0021] Step 2. Orientation of the crystal

[0022] The orientation adopts an X-ray orientation instrument; the crystal cutting adopts an X-ray orientation instrument;

[0023] Step 3. Crystal cutting

[0024] For the crystal cutting, an X-ray orientation instrument is used to process the two end faces of the laser crystal into Brewster’s angles, and the parallelism is ensured; the Brewster’s angle of the crystal cutting, the incident light is at the incident interface When it is incident at Brewster's angle, the refracted light can propagate along the direction parallel to the side of the optical element, and enter the air medium through the revers...

Abstract

The invention discloses a method for processing Nd: YAG laser crystal through a Brewster angle. The method comprises the following steps: material selection, orientation, cutting and polishing of crystal, wherein in material selection, He-Ne laser is utilized to irradiate scattering points visible to the naked eyes; in orientation, an X-ray orientation instrument is adopted; during crystal cutting, the X-ray orientation instrument is adopted; and during polishing, a four-axis polishing and grinding machine for diamond powders is adopted for polishing. The processing method based on the Brewster angle is suitable for laser crystal processing, is simple and reliable in processing process, is good in university, does not need film coating, is high in laser damage threshold and improves service life of the crystal and reduces processing cost thereof.

Description

technical field [0001] The invention relates to the field of functional crystal processing, in particular to a processing method suitable for laser crystals. Background technique [0002] Today, the processing of laser crystals is generally oriented, cut and polished, and then coated. After coating optical components, the performance of optical components can be significantly improved. "Where there is light, there is film" is a maxim in the field of optics. Coating after polishing of optical components has always been an important part of the field of optics. Coating, as a proprietary technology, has made important contributions to the development of optical equipment. [0003] However, the coating process itself is complicated, and the polishing requirements for optical components are high. The overall cost of the coated optical components is high, and the coating is easy to cause the film to fall off, the surface finish is reduced, and the coating layer is easily damaged b...
