化学处理增强光学材料的抗激光破坏强度

Increase of Laser Damage Resistance of Optical Materials by Chemical Treatment

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。

Experimentul results of increased laser damage resistance for optical materials by chemical treatment are reported. Laser surface damage thresholds of K 9 and K 2 glass after acid etching are increased by a factor of 3 and 4, respectively. Good effects are also obtained for crystal and fused silica. The strengthening mechanism of the laser damage resistance of optical materials by chemical treatment is analyzed.
