摘要
为了研究拉盖尔-高斯光束与熔石英相互作用, 采用仿真计算的方法对TEM00,TEM01和TEM10 3种模式拉盖尔-高斯光束辐照下的熔石英的温度和热应力进行研究, 取得了仿真数据。结果表明, 激光光强的空间分布影响材料的温度分布和应力分布; 温度的积累效应明显, 经过连续激光脉冲作用后材料温度持续升高, 焦点区域超过1900℃; 温度梯度导致热应力产生, 局部热应力接近50MPa。该仿真结果为熔石英的加工提供了有益的参考。
Abstract
In order to study the interaction of Laguerre-Gaussian beam and fused quartz, the method of simulation calculation was adopted to study the temperature and thermal stress of the fused quartz irradiated by 3 modes of Laguerre-Gaussian beam (TEM00, TEM01, TEM10). The simulation data were obtained. The results show that spatial distribution of laser intensity affects temperature distribution and stress distribution of the materials. The accumulation effect of temperature is obvious. After continuous laser pulse action, the material temperature continues to rise. The focus area is over 1900℃. The temperature gradient leads to thermal stress. The local thermal stress is close to 50MPa. The simulation results provide the useful reference for the processing of fused silica.
