Description

technical field [0001] The invention belongs to the technical field of solid-state lasers, and in particular relates to an optical cabin environment monitoring device and a control method for high-power solid-state lasers. Background technique [0002] High-power solid-state lasers are precision optoelectronic devices that have high requirements for ambient temperature and humidity. The power of high-power solid-state lasers is high, and all related functional devices work in a high-power state, which is easy to cause heat deposition, cause their own temperature to rise, and affect their working performance, which in turn leads to the drift of the output laser spectrum and power of the laser, which seriously affects the laser. output beam quality. Therefore, the necessary cooling technology is adopted to make it work at a suitable temperature to ensure the normal operation of various components in the laser. [0003] In the actual operation of high-power solid-state lasers...
