报道了用化学处理方法提高光学材料的抗激光破坏强度实验结果，化学处理使Ｋ９和Ｋ２玻璃的激光损伤阈值分别提高３倍和４倍，对晶体和熔石英的化学处理也取得了较好的效果。并对加固机理作了分析 The experimental results of improving the anti-laser damage strength of optical materials by chemical treatment are reported. The chemical treatment increases the laser damage threshold of K9 and K2 glass by 3 times and 4 times respectively, and also achieves good chemical treatment on crystal and fused quartz effect. And the strengthening mechanism is analyzed
