Abstract

The invention discloses a folded cavity laser and relates to the technical field of lasers. The folded cavity laser divides the circle with radius r into 5 equal parts, and respectively sets a half-reflecting mirror and four total reflecting mirrors on the 5 equal-dividing points, wherein, the angle of the total reflecting mirror at the end of the optical path can be adjusted, and the rest of the half-reflecting mirrors and total reflector are fixed. When adjusting, it is only necessary to adjust the total reflection mirror at the end of the optical path, which avoids the complicated adjustment process. Moreover, through this geometric design, the compression efficiency of the resonant cavity can be effectively improved, the maintenance of the laser is facilitated, and the laser is relatively stable.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to a folded cavity laser. Background technique [0002] The resonator is an important part of the solid-state laser, and the mode characteristics, beam quality, stability and output power of the laser depend to a large extent on the design of the laser resonator. Therefore, the resonator is the core of the laser, and the design of the resonator is one of the hotspots and difficulties in current laser research. [0003] At present, the resonant cavity of the existing folded cavity laser is generally a V-shaped cavity, a Z-shaped cavity, a U-shaped cavity or an M-shaped cavity. The traditional folding cavity design has the following defects: (1) The folding efficiency is not high. To achieve high folding efficiency, it is necessary to increase the number of mirrors and increase the cost. At the same time, curved mirrors will be introduced to cause dispersion of the beam in the cavity;...
