【摘要】 报道了ＭｇＦ２晶体１．０６μｍ激光损伤阈值和损伤形貌。研究了用ＣＯ２、ＸｅＣｌ和Ｃｕ蒸气三种不同的激光对ＭｇＦ２进行激光预辐照加固和酸腐蚀加固。结果表明，Ｃｕ蒸气激光加固效果最佳，其次是酸腐蚀和ＸｅＣｌ激光预辐照，并对加固机理进行了分析更多还原

【Abstract】 The laser damage thresholds and morphologies of MgF 2 crystals at 1.06 μm are reported. Strengthening of the MgF 2 crystals is investigated by laser pre irradiation and acid etching with CW CO 2, XeCl and Cu vapour lasers. Ihe results show that the Cu vapour strengthening effect is the optimum and the next are acid etching and XeCl laser pre irradiation. Strengthening mechanism is analyzed.更多还原
