摘要

在高功率激光应用的背景下,我们研究了热处理对CO2激光对熔融二氧化硅样品激光损伤部位的影响。对炉内等温退火进行了研究,并与二氧化碳激光局部退火进行了比较。我们研究了等温退火前后的形貌、残余应力的演变以及在355nm、3ns处测量的激光损伤阈值。结果表明,在1050℃下退火12 h后,材料的初始激光损伤概率显著提高。这些结果与基于有限元法的热-力学模型的模拟结果进行了比较。

Heat treatment of fused silica optics repaired by CO2 laser
In the context of high power laser applications, we study the effect of a heat treatment on CO2 laser mitigation of laser damage sites on fused silica samples. The isothermal annealing in a furnace is investigated and then compared to the local annealing by CO2 laser irradiation that is applied to enhance laser damage resistance on mitigated sites. Before and after isothermal annealing, we study the sites morphology, the evolution of residual stress and the laser-induced damage threshold measured at 355nm, 3ns. The results show that the initial laser damage probabilities were significantly improved after annealing at 1050°C for 12 hours. These results are compared to simulations with a thermo-mechanical model based on finite-element method.
