Abstract

In a recent paper, Desai et al. (1994) have reported the observed characteristics of the specularly reflected laser light from a copper plasma created by laser irradiation of a planar copper target. They have measured specular reflection, and attributed the observed diffusivity of specularly reflected radiation to the curved and rippled surface at the radiation turning point in the plasma. The aim of this comment is to reanalyse the possible causes for the diffusion of specular reflection relevant to their experimental conditions.
