摘要
在广泛调研相关文献的基础上,基于热弹性理论,计算了熔石英在DF激光辐照下的温升曲线和热应力场分布曲线,分析了熔石英的激光破坏机理。研究结果表明,激光辐照下的熔石英的温度场分布和应力场分布与辐照激光的光场分布、激光功率密度以及激光的辐照时间等因素有关。
Abstract
Based on the extensive research of thermoelasticity, the temperature and thermal stress-field distribution curves of the fused silica are studied under irradiation of DF laser. It can be shown that the temperature field distribution and thermal stress field distribution of the fused silica irradiated by DF laser depend on the field distribution, power density and irradiation time of lasers.
