熔石英亚表面三维Hertz锥形划痕附近光强分布的数值模拟

The main factor of laser induced damage is the modulation caused by the scratch in the subsurface of the fused silica.The three-dimensional Hertzian conical scratch(HCS) model on the exit surface is establised in this article.Three-dimensional finite-difference time-domain method is used to calculate and simulate the electric field intensity distribution in the vicinity of HCS.The effects of depth,radius and gradient angle of the HCS on incident light field modulation are analyzed,respectively.The results s...
