Abstract

The invention provides a mixer crystal four-dimensional high-precision adjustment mechanism, and relates to a high-throughput large-caliber high-precision optical element frequency conversion device. The mixer crystal four-dimensional high-precision adjustment mechanism is used for achieving four-dimensional high-precision adjustment of a mixer crystal in narrow space in a frequency conversion module in an inertial confinement laser nuclear fusion device in China. 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-diameter and high-precision optical element frequency conversion device, in particular to a four-dimensional high-precision adjustment mechanism for a frequency mixing crystal. Background technique [0002] The attitude adjustment of the frequency 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, and 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, it is necessary to realize online adjustment and improve the positioning accuracy. At present, there is no mature device to realize the batch h...
