Problems solved by technology

[0002] Solid-state lasers are currently very commonly used lasers, and many solid-state lasers are high-power lasers. For high-power lasers, the heat generated during operation is very large. The main reason for the heat is due to pumping Insufficient use of light and poor cooling capacity of heat sinks
The high-power solid-state lasers in the prior art often adopt an intermittent working mode when facing this kind of problem, that is, if the heat dissipation does not occur in time and leads to overheating, the laser will stop working at this time

Abstract

A high-power solid laser good in heat dissipation performance is characterized in that an adopted gain medium comprises an M-shaped part and conical parts arranged on two wings of the M-shaped part. The gain medium is centrally symmetrical about the M-shaped part. The M-shaped part comprises four arms comprising the first arm (22), the second arm (23), the third arm (23) and the fourth arm (24) from left to right, the four arms are combined to be in an M shape, the included angles between any two arms are equal, and the angle is from 20 degrees to 60 degrees.

Description

technical field [0001] The invention relates to a laser, mainly a solid-state laser, and belongs to the technical field of optoelectronics. Background technique [0002] Solid-state lasers are currently very commonly used lasers, and many solid-state lasers are high-power lasers. For high-power lasers, the heat generated during operation is very large. The main reason for the heat is due to pumping Insufficient use of light and poor cooling capacity of the radiator. The high-power solid-state lasers in the prior art often adopt an intermittent working mode when facing this problem, that is, if the heat dissipation does not occur in time and leads to overheating, the laser will stop working at this time. This has caused great changes to daily scientific research and study work, and for this, we have proposed the present invention. Contents of the invention [0003] In order to solve the above problems, the present invention proceeds from two aspects. On the one hand, the ...
