Description

Technical Field

[0002] With the development of science and technology, the development of ultra-stable FP cavities used in ultra-stable frequency and ultra-narrow linewidth lasers has been gradually optimized. During the use of the FP cavity, the reflectivity and smoothness of the cavity mirror determine the stability of the FP cavity. In the existing FP cavity mirror processing, most of them are polished manually, but the polishing efficiency is low. Some of them are polished mechanically, but the mirror surface cannot be effectively fixed. The mirror surface is easily displaced during the polishing process, resulting in polishing defects that affect use.

[0003] When the existing polishing device is in use, the mirror surface is placed and polished only by the provided grooves, and the mirror surface cannot be effectively fixed. During the polishing process, the mirror surface may warp or rotate. When warping or rotating occurs, it may cause defects such as uneven polishing and incomplete polishing, thereby affecting the subsequent use of the mirror surface. Utility Model Content
