Problems solved by technology

So far, pulsed disk lasers with small aperture and high energy density have great application prospects and markets, so there is an urgent need for an especially high-efficiency cooling device to improve the beam quality of disk lasers due to thermal lens effects. Poor, poor stability and other factors that restrict the performance of disk lasers are further reduced

Abstract

The invention discloses a micro-channel metal foam disk laser crystal cooling device, which comprises a disk laser crystal, metal foams and a micro-channel plate water circulation system, wherein the pore diameter of the metal foams is within 0.5 mm, and a copper tungsten material is selected. The micro-channel metal foam disk laser crystal cooling device has the advantages that the foam metal cooling device is delicately introduced to a disk laser crystal back cooling field, the metal foam structure features and the micro-channel water circulation system are mutually combined thoroughly, the cooling water can cool the disk crystal uniformly, and the crystal cooling efficiency is greatly enhanced.

Description

technical field [0001] The invention relates to the field of crystal cooling of a dish laser, in particular to the field of a microchannel metal foam disk laser crystal cooling device. Background technique [0002] Yb:YAG disk laser has become one of the most popular high-power solid-state lasers in recent years, and has a good development prospect. Yb:YAG crystals have good laser properties such as absorption bandwidth, long fluorescence lifetime, and high quantum efficiency; the revolutionary design concept of the geometric structure of the disk laser crystal makes it have fast cooling speed, good heat dissipation performance, high beam conversion efficiency, It has many advantages such as good beam quality and low operating cost. The good laser performance of Yb:YAG crystal and the innovative concept of disk crystal are the key to the success of Yb:YAG disk laser. But even the Yb:YAG crystal still generates heat when it works; and the revolutionary design of the disk la...
