Abstract

The temporal evolution and kinetic properties of material particles ejected from the surface of fused silica under nanosecond laser irradiation are investigated using a time-resolved microscope system. The experiments provide information on the particle size, shape, and speed as a function of delay time, as well as on the duration of the material ejection process. The results suggest that the processes involved are much more complex than those predicted by current models.
