Abstract

The invention discloses a solid laser gain module cooled by supersonic low-temperature gas. The module comprises a supersonic spray pipe, solid laser gain medium sheets, a first quartz window and a second quartz window, wherein low-temperature gas generated by the supersonic nozzle flows through the surfaces of the solid gain medium sheets to realize heat exchange. N + 1 flow channels are formed by the first quartz window, the second quartz window and N solid gain medium sheets. The solid laser gain module can adopt an end surface pumping mode or a side surface pumping mode. The solid laser gain module provided by the invention has the advantages of simple heat exchange equipment structure, convenience in use and the like.

Description

technical field [0001] The invention belongs to the field of laser technology, and in particular relates to a solid-state laser gain module and a laser device cooled by supersonic low-temperature gas. Background technique [0002] The waste heat generated by the gain medium of the solid-state laser will seriously affect the output power, efficiency, beam quality and stability of the laser system. The development of new, higher-efficiency heat transfer technology is of great use value for high-energy solid-state lasers. In recent years, a new technology of using cryogenic gas to cool the solid gain medium has been developed. By increasing the temperature difference between the gas and the laser gain medium, a larger heat transfer flux can be obtained. In addition, due to the small thermo-optic coefficient of the gas, cooling the gas has little effect on the beam quality of the laser. A typical laser system, such as the DiPOLE laser system in Europe, uses helium at a tempera...
