Embodiment Construction
[0010] The present invention will be further described in conjunction with the accompanying drawings. The constant temperature structure adopts a fully cooled bottom plate. The cooling circulating water flows in from one end of the bottom plate, flows through the entire bottom plate, and then flows out from the other end; all laser components are installed on the water-cooled bottom plate. Then the laser is in a constant temperature working environment. The water-cooling source device adopts a constant-temperature water-cooling device refrigerated by an ordinary compressor, and the temperature instability is <±1°C; or a constant-temperature water-cooling device adopts semiconductor refrigeration, and the temperature instability is <±0.1°C.
[0011] The dehumidification structure of the present invention adopts a sealed cabinet, puts all laser components in it (only the laser input and output holes are left), and places an electronic dehumidifier in the sealed cabinet for suctio...
