Abstract

The invention relates to a surface microdefect search and repair device for large-diameter KDP crystal elements, in particular to a surface microdefect fast search and micro-milling repair device for large-diameter KDP crystal elements, and aims to solve the problem that presently no device for fast research and micro-milling repair of surface microdefects in large-diameter KDP crystal elements is provided. An integral platform fitting assembly is fixed on a bottom large flat plate. A bottom platform fitting assembly is fixed on the integral platform fitting assembly. A crystal moving platform fitting member is fixed on the integral platform fitting assembly. A crystal microscope moving platform is fixed on the integral platform fitting assembly. First and second drag chains are connected with the crystal moving platform fitting member through guide rail and drag chain connecting blocks. The lower portion of a crystal microscope moving platform support is connected to the upper end face of the integral platform fitting assembly. The crystal microscope moving platform is mounted on the crystal microscope moving platform support. The device is applicable to surface microdefect fast research and micro-milling repair for large-diameter KDP crystal elements.

Description

technical field [0001] The invention relates to a device for searching and repairing micro-defects on the surface of a large-diameter KDP crystal element. Background technique [0002] With the increasing depletion of fossil energy on the earth, nuclear fusion energy has become the most ideal energy source for the subsequent development of mankind due to its inexhaustible and clean advantages. KDP crystals with excellent optical properties are used as optical switches and frequency doubling crystals, and play an important role in inertial confinement fusion devices. However, in the process of ultra-precision machining and high-energy laser targeting to produce nuclear fusion, the surface of KDP crystals is prone to micro-defects in the form of micro-cracks or ablation. If measures are not taken to deal with them in time, these micro-defects will continue to grow in the subsequent laser targeting process, and even the entire crystal element will be damaged. At present, most...
