Abstract

The invention relates to a nonlinear large-aperture optical element clamping device, in particular to a nonlinear large-aperture optical element clamping device capable of achieving definite value axial load application. The nonlinear large-aperture optical element clamping device capable of achieving definite value axial load application solves the problem that harmonic conversion efficiency of a nonlinear large-aperture optical element is reduced because the nonlinear large-aperture optical element deforms easily under the action of gravity and clamping force. The nonlinear large-aperture optical element is placed on a supporting frame; locating edge blocks are arranged on the periphery of the supporting frame in a distributed mode and are fixedly connected with the supporting frame, plastic staple horizontal installation holes are formed in the locating edge blocks, and plastic staples penetrate through the plastic staple horizontal installation holes and make contact with the nonlinear large-aperture optical element; elastic pressing sheets are arranged on the periphery of a light-facing face of the nonlinear large-aperture optical element in a distributed mode, a rigid pressing sheet is arranged on each elastic pressing sheet, and the elastic pressing sheets and the rigid pressing sheets are connected with the locating edge blocks through load applying screws; a torque wrench acts on the load applying screws. The nonlinear large-aperture optical element clamping device capable of achieving definite value axial load application is applied to experimental schemes for full-circumferential clamping and definite value axial load application of the nonlinear large-aperture optical element.

Description

technical field [0001] The invention relates to a clamping device for a nonlinear large-diameter optical element, in particular to a clamping device for a nonlinear large-diameter optical element that realizes the application of a constant value axial load. Background technique [0002] The nonlinear large-aperture optical element used in the field of laser nuclear fusion undertakes the task of harmonic conversion of high-energy lasers. Due to its large diameter-thickness ratio, it is prone to deformation under the action of gravity and clamping, resulting in its harmonic Conversion efficiency drops. In the traditional clamping methods of large-aperture optical components, three-point or four-point axial clamping is generally used, or glue is used in the radial direction. In these clamping methods, the deformation of large-aperture optical components is relatively large, which cannot meet the requirements. Harmonic conversion requirements for high energy lasers. Reasonable...
