摘 要:Spontaneous optical emission properties of laser-produced plasma during laser damage events at input and exit surfaces of fused silica were retrieved and *** show that plasma at the input surface is much larger in size and exhibits significantly higher electron number density and excitation temperature,even when smaller laser energy was *** effect was attributed to the stronger laser–plasma coupling at the input *** addition,a strong continuum background containing three peaks at 1.3eV,1.9eV,and 2.2eV was observed at the exit surface,and possible origins for this effect are also discussed.
