| 摘 要： | 在得到高斯型短脉冲激光辐照光学薄膜温度分布的基础上,基于最大剪应力理论建立了光学薄膜发生迎光剥落的理论模型,得到了发生损伤的相应的应力分布。通过数值计算,分析了在短脉冲激光辐照时ZrO2薄膜的损伤情况,并计算出相应的损伤阈值。对理论计算与实验结论进行了比较,验证了理论模型的合理性。

| Abstract: | A physical mold of ZrO2 film peeling caused by ns laser based on the theory of the most shearing strength is established. The distributions of stress and the relationship between the radius of peeled film and the energy of the incidening laser are studied. Through analyses, it is validated that the physical model is in accordance with the result of the experiment. The damage threshold of peeled film and the curve of the peeled film radius and the energy of the incidening laser are nearly the same as result of the experiment. The width of the pulse and the radius of facula have little effect on the damage threshold. |
