摘要
通过对纳秒和飞秒高功率激光脉冲辐照下透明电光陶瓷掺镧锆钛酸铅(PLZT)的表面损伤形貌和物理形态的分析,调整辐照脉冲能量在线观测表面损伤几率,研究了不同能量等级的纳秒和飞秒高功率高斯光束辐照同一电光陶瓷表面的激光损伤,测得纳秒激光损伤阈值约为485 MW/cm2。还分析了辐照损伤斑直径随辐照能量的变化,辐照损伤的损伤深度随损伤直径变化,以及材料中的缺陷引起的损伤形貌。对比分析了纳秒激光和飞秒激光辐照下PLZT电光陶瓷表面损伤形貌的不同,并给出了一些可能的理论解释。
Abstract
Damage morphologies on lanthanum doped lead zirconate titanate (PLZT) surface induced by nanosecond and femtosecond pulses irradiate. Different levels of the high power nanosecond and femtosecond pulses are irradiation on the surface of PLZT, where the pulses are near Gaussian beams. The damage probability is observed on line and the suitable powers of the pulses are adjusted. The nanosecond pulse induced damage threshold of PLZT is 485 MW/cm2. The variations of the damage spot diameters versus the energy irradiation are analyzed. The variation of the damage depth versus the damage diameters and the damage morphology induced in the defect in the ceramic are also detected and recorded. The damage morphologies induced by nanosecond and femtosecond pulses are also contrasted. And some possible explanations due to the difference are given.
