| 摘 要： | 针对3个光斑尺寸的CO2激光辐照尺寸小于400 m损伤点后得到的修复点，从4个方面对损伤修复点经355 nm激光辐照后的损伤概率分别进行研究。结果表明，根据修复光斑尺寸或损伤点尺寸分别讨论修复点的损伤概率，更能反映修复点的抗激光损伤能力。通过分别讨论可以看出，采用小光斑CO2激光辐照损伤点或者修复尺寸小于200 m的损伤点，修复成功率超过90%。同时，可以通过损伤修复点的激光损伤阈值都服从正态分布的规律来预测修复点的损伤概率。

| Abstract: | The damage sites with sizes less than 400 μm were mitigated with CO2 laser beams of three sizes. The damage probabilities of mitigated damage sites irradiated with 355 nm laser are discussed separately from four aspects. The results show that it is better to manifest the damage resistance capability of mitigated sites via discussing their damage probabilities according to the sizes of CO2 laser beam and damage site separately. Separate discussions show the mitigation efficiency exceeds 90% if the damage site is irradiated by a CO2 laser beam with size small enough or the size of the mitigated damage site less than 200 μm. In addition, the damage probability of mitigated site can be predicted from the law that the laser-induced damage threshold of mitigated damage sites obeys the normal distribution. |
