Description

technical field [0001] The invention relates to a laser, in particular to a mechanical shutter of a high-power laser. technical background [0002] The mechanical shutter is a device that controls the closing and opening of the laser emitted from the axis of the resonator, and guides the laser output. It is an important part of the axial fast flow gas laser. The mechanical shutter is mainly composed of a total reflection mirror that can control its movement to the laser optical path and change the laser optical path, an absorption shell device with cooling function for absorbing the laser reflected by the total reflection mirror, and a guiding device for simulating the laser direction when the laser is output. , and the housing of the mechanical shutter. The performance evaluation of the shutter mainly involves the action sensitivity of the motion system, the ability of the energy absorbing mechanism to absorb and process energy, and the guiding stability of the guiding sys...
