    A mechanical structure for two-dimensional fast-steering active cooling mirror was designed to control precisely the transmission direction of laser emitting and to reduce the mirror thermal distortion to improve laser beam quality. Based on the design and fabrication principles for the high power laser reflector, an active cooling mirror was adopted to improve the beam quality by reducing the mirror thermal distortion which can control the mirror distortion less than 0.1 μm. Then, an equipment was designed from three aspects in the framework, driver, controlling system and the angle measurement element. By using a x-y axis framework structure,the effect of the cooling water tube for mirror on axis system could be reduced and rotation precision of the axis system was less than 2″. The test result was analyzed and it is shown that the mechanical structure works stably and reliably, stabilization precision is less than 1″,which can satisfy the system requirements of stabilization, higher precision and rapid speed for controlling and correcting accurately the transmission direction of the beam, and can be applied widely to the high power laser system.
