Abstract
Spatial profile of ablation front is observed under the irradiation of spatially modulated 0.27-μm laser beam. Propagation depth of the ablation front is derived by means of various methods which detect x-ray radiation from aluminum substrates overcoated with polyethylene layers of different thicknesses. A higher mass ablation rate is observed for the UV laser than the longer wavelength lasers. However, observation with an x-ray television camera shows that the spatial nonuniformity in the laser beam is projected on the ablation front surface without substantial smoothing.This publication has 11 references indexed in Scilit:
