| 摘 要： | 本文首次把调制与脉冲光热偏转技术同时置于激光损伤测试装置之中,用以进行光学薄膜激光损伤的实时研究.初步实验结果表明,该方法不仅有助于确定损伤阀值,也有助于分析损伤形貌和损伤过程,包括样品损伤前的行为及样品在重复频率激光作用下损伤的累积效应.

| Abstract: | Photothermal deflection technique (PDT) is employed to make in-situ investigation of laser-induced damage in optical coatings. Primary experimental results show that the technique is capable of providing a lot of new information not only about the damage thresholds but also about the damage morphology and the damage process, of which of particular interest are the predamage behavior of optical coatings and the cumulative effect of the damage. |

| Keywords: | in-situ investigation photothermal deflection laser damage optical coating. |
