Description

technical field [0001] The invention relates to a large-diameter crystal frequency multiplication conversion device, in particular to a large-diameter crystal frequency multiplication conversion device for realizing crystal temperature regulation in a vacuum environment. Background technique [0002] Frequency doubling conversion technology is an important method to obtain a laser with a specific wavelength. It mainly uses the frequency doubling effect of crystals such as KDP, DKDP, ADP, etc. to obtain high-frequency, high-energy lasers. Due to the high temperature sensitivity of crystals, in The frequency doubling efficiency of the crystal can be greatly reduced under a small temperature change, so high-precision temperature control is required for the crystal. However, in the process of using the large-diameter crystal frequency doubling mechanism, the temperature of the large-diameter crystal cannot be effectively controlled, and this problem needs to be solved urgently. ...
