Description

technical field [0001] The invention relates to an accessory part of a laser, in particular to a cooling water device for an all-solid-state high-power laser suitable for mobile processing. Background technique [0002] The main parts of all-solid-state lasers are palladium bars, crystal rods, optical fibers, lenses, etc., and these parts are easily damaged, so their protection is the focus of the control system, and the protection method for these parts is mainly water-cooled It is cooled in real time. [0003] Traditional laser water cooling uses only one cooling water tank and one input and output waterway, which simultaneously cools the palladium bar heat sink, crystal rod and lens of the laser head. In this way, the temperature of the cooling water at all cooling points is consistent, but in fact the temperature of each point affects each other and changes from time to time, and the temperature requirements of each component are not the same. For example, the protecti...
