The invention discloses an optical cabin environment monitoring device for a high-power solid laser and a control method thereof. The monitoring device comprises: a cooling water circulating unit; anoptical crystal temperature control module, including a base fixed in an optical cabin and in which cooling water circulates, a heat-conducting carrier for mounting and fixing the optical crystal, a first temperature sensor arranged in the heat-conducting carrier, and a semiconductor refrigerating unit arranged between the heat-conducting carrier and the base; a cabin air quality monitoring module, including a temperature-humidity sensor arranged in the optical cabin; a controller in communication connection with the first sensor, the semiconductor refrigerating unit and the temperature-humidity sensor. Internal operation parameters of a cabin are measured in real time and precisely controlled in high integrity manner in response to the special environment in the optical cabin; the environmental conditions, such as temperature, humidity and cooling water state, are monitored in real time, and precise temperature control is provided for optical elements.

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...
