| 摘 要： | 采用溶胶-凝胶法制备了含有吸收性杂质和非吸收性杂质的SiO2增透膜，采用波长为1 064 nm的激光对其进行了小光斑激光预处理，对比研究了预处理前后的激光损伤差异，研究表明：激光预处理对于洁净的SiO2薄膜影响不大；含10 μm SiO2颗粒杂质的样品微透镜效应很明显，容易成为损伤起始的种子，激光预处理后情况有所改善；含有CeO2颗粒杂质的样品表现出了很强的吸收性质，损伤阈值降低到不足洁净样品的一半。所有样品激光预处理后损伤形貌未发生变化，透光率峰值均有约50 nm的蓝移。

| Abstract: | Three kinds of anti-reflective SiO2 films, without impurities, with SiO2 particulate impurities and with CeO2 particulate impurities, were deposited on K9 glass by sol-gel dip-coating method. The influence of impurities on laser-induced damage of films was investigated before and after preconditioning with a 1 064 nm Nd:YAG pulsed laser. No obvious change in morphologies and damage threshold appears for pure films after conditioning. For the films with SiO2 impurities, 10 μm-size SiO2 particles show obvious micro-focusing effect and act as damage-initiating seeds, which can be removed by conditioning. Moreover, the samples with CeO2 impurities have intense absorbing character, and their laser-induced damage threshold is les |
