Problems solved by technology

However, the main defects of this pump light multi-pass transmission system are: the distribution of light spots on the surface of the parabolic mirror is relatively scattered, the utilization rate of the effective area of ​​the parabolic mirror is low, the heating of the parabolic mirror is uneven, and the surface distortion is serious during high-power operation. As a result, the thermal distortion and thermal

Description

technical field [0001] The invention belongs to the field of laser technology, and more specifically relates to a pump light multi-path transmission system with two discs connected in series and a disc laser. Background technique [0002] Disk solid-state laser is a high-end high-power solid-state laser. The essential difference between it and the traditional solid-state laser lies in the shape of the laser working material. The disc laser changes the traditional rod-shaped crystal into a disc-shaped crystal. The thickness of the crystal is 0.2mm ~ 0.4mm. The pump light is incident from the front of the crystal, and the cooling is realized on the back of the crystal. Since the crystal is very thin and the diameter and thickness are relatively large, the cooling effect of the crystal is good, which is conducive to obtaining high conversion efficiency and high efficiency. Laser output with average power and high beam quality. [0003] One of the greatest advantages of disk l...
