Description

technical field

[0001] The invention belongs to the technical field of solid-state lasers, in particular to a method for reducing thermal stress of a heat capacity laser medium. Background technique

[0002] Compared with other types of lasers, solid-state lasers pumped by semiconductor lasers have output characteristics such as multi-wavelength, short-wavelength, tunable, short-pulse, and high repetition rate. They are widely used in defense industry, industrial processing, aerospace, medical and other fields. application prospects.

[0003] For a long time, solid-state lasers ( S solid S tate L Aser, referred to as SSL) output power has been restricted by waste heat generated during work, it is difficult to obtain a high average power output. Although the laser diode (LD)-pumped solid-state laser (DPSSL) improves the light-to-light conversion efficiency and effectively reduces the generation of waste heat, most SSL systems still need real-time cooling during operation,...
