Abstract

The present invention provides a gain module of a tilt aberration self-compensating type direct liquid-cooling thin-disk laser. The gain module comprises heat dissipation channels, an adapter, gain plate strips and a packaging shell. The adapter is composed of run-through flow channels and an entity portion, wherein the run-through flow channels and the entity portion are staggered to form the adapter. The heat dissipation channels are divided into a group A of heat dissipation channels and a group B of heat dissipation channels. The group A of heat dissipation channels and the group B of heatdissipation channels are connected with the run-through flow channels of the adapter in opposite directions in a staggered mode. The gain plate strips are fixed between the two run-through flow channels of the adapter. The packaging shell is covered outside the gain plate strips and is fixedly connected with the adapter. According to the invention, two groups of heat dissipation channels are arranged. In this way, the cooling liquid between every two gain plate strips is opposite in flow direction. The aberration can be automatically compensated in the flow direction of the cooling liquid. The output power of the direct liquid-cooling thin-disk laser is improved.

Description

technical field [0001] The invention relates to the field of lasers, in particular to a gain module of a direct liquid-cooled sheet laser with tilt aberration self-compensation. Background technique [0002] High-energy solid-state lasers have broad application prospects in advanced industrial manufacturing, high-power physical science research, energy, and new concept weapons. Simultaneously achieving high power and high beam quality laser output has always been the focus of solid-state laser research at home and abroad. With the increase of laser output power, waste heat has become an important factor restricting the development of high-energy lasers. Severe thermal effects will reduce the output power of the laser on the one hand, and on the other hand will reduce the beam quality of the laser and may even cause damage to the gain medium. In the process of addressing thermal effects, lasers of various configurations have emerged. Including reflective thin-sheet lasers,...
