According to the mixer crystal four-dimensional high-precision adjustment mechanism, a mixing mechanism is arranged in a frequency multiplication box body, the lower end of a deflection angle modulation frame is arranged in a pitching adjustment frame in a rotating mode, the side walls of a mixing spacing adjustment rack are arranged on the lower portions of the side walls of the pitching adjustment frame in a rotating mode, a polarization state adjustment frame is inlaid on the end surface of the deflection angle modulation frame, a mixing gap adjustment base is arranged below the mixing spacing adjustment rack, a mixing horizontal moving adjustment mechanism is arranged between the mixing gap adjustment base and the mixing spacing adjustment rack, and a polarization state adjustment mechanism is arranged on the polarization state adjustment frame. The mixer crystal four-dimensional high-precision adjustment mechanism is used for posture adjustment of the mixer crystal.

Description

Technical field [0001] The invention relates to a high-throughput large-aperture high-precision optical element frequency conversion device, in particular to a four-dimensional high-precision adjusting mechanism for a mixing crystal. Background technique [0002] The attitude adjustment of the mixing crystal is an important part of the frequency conversion module in the vacuum controllable high-throughput large-aperture optical focusing and frequency conversion system. It plays an important role in the energy conversion and transmission characteristics of the laser beam under high-intensity operating conditions. The adjustment method and adjustment accuracy of the best matching angle of the mixing crystal put forward higher requirements. In addition, in order to save the time of disassembly and assembly, online adjustment is required to improve the positioning accuracy. At present, there is no mature device to realize batch high-precision adjustment of the mixing crystal in the f...
