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 with dual temperature control modes for crystal temperature regulation. It uses constant temperature circulating water as a heat source to jointly heat a sealed cavity and The crystal frame is a device for heating large-diameter crystals and maintaining high temperature control accuracy of large-diameter crystals. Background technique [0002] Frequency doubling conversion technology is an important method to obtain high-energy lasers. It mainly obtains high-frequency, high-energy lasers through the frequency doubling effect of crystals such as KDP, DKDP, and ADP. 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. In many fields, the demand for large-beam ...
