Abstract

The invention discloses a micro-channel radiator structure which comprises a cover plate which is provided with a working medium inlet and a working medium outlet; a metal base which is arranged belowthe cover plate in a sealing manner; a first micro-channel structure which is arranged in the cover plate and the metal base sealing body in the first direction; a second micro-channel structure which is arranged in the cover plate and the metal base sealing body in the second direction and is communicated with the first micro-channel structure, the working medium inlet and the working medium outlet; and a micro-channel shunting structure which is arranged in the cover plate and the metal base sealing body and is communicated with the first micro-channel structure.

Description

technical field [0001] The invention relates to the technical field of thermal management of semiconductor lasers, in particular to a locally strengthened microchannel heat sink for laser crystals in end-pumped slab lasers and a manufacturing method thereof. Background technique [0002] Laser technology is an important science and technology developed in the 20th century, and has been widely used in military, medical, material processing and other occasions. Among them, the laser diode pumped all-solid-state laser has the advantages of high efficiency, high reliability, and high beam therapy. These advantages are especially obvious in the end-pumped slab laser. However, due to the low thermal conductivity of the laser crystal in the end-pumped slab laser, the risk of thermal lens effect and thermal fracture damage largely limits the increase of laser power. Therefore, the heat dissipation of laser crystals has become an urgent problem to be solved. [0003] The article "T...
