Abstract
The expansion dynamics of laser-induced plasma (LIP) at front and rear surface of fused silica under 1064 nm nanosecond laser irradiation was investigated with fast photography, shadowgraphy and interferometry. Self-emission images of LIP show that the rear surface plasma (RSP) splits into a fast and a slow component at tens of nanoseconds delay after laser irradiation while the front surface plasma (FSP) does not split. Moreover, the FSP is identified to mainly contain free electrons while the RSP includes ejected neutrals. Thermal emission of superheated neutrals is suggested to be responsible for the generation of slow component.
