高能激光用无氧铜镜设计和加工

无氧铜镜在高能激光的光路中是重要元件,起到扩束、折转光路的作用.这种无氧铜镜因材料内部晶格细腻、不具有氧逆集热现象而无冷却系统.材料为高纯度电解铜,经中压锻造后使材料内部晶格更细腻、无结块、形成无氧铜镜基板,稳定化处理后消除内应力,经机械加工达到图纸要求.通过工具显微镜检测无氧铜镜表面是否存在结块,如果无异常现象便可进...

Design and Processing of Oxygen-free Copper Mirror for High-energy Laser

Oxygen-free copper mirror is important in high-energy laser optical components,while playing a beam expander and refracting the optical path. The oxygen-free copper mirror hasn’t cooling system for fine crystal lattice within the material and without the phenomenon of oxygen. The material is high-purity electrolysis copper by medium-pressure forging, with more delicate lattice,without agglomeration, forming the oxygen-free copper mirror substrate. The internal stress is eliminated by stabilization treatment. It can meet the drawing requirement from mechanical processing. The oxygen-free copper mirror surface is detected using microscope. If there is no abnormal phenomenon, then turn into nickel plating. The grinding and polishing accord to the working procedure, and detected by the laser interferometer, so as to meet the technical requirements and achieve the targets of the oxygen-free copper mirror.
