Abstract

An experimental investigation of the effect of linearly polarized high-energy pulsed laser light, normally incident on a carbon thin film, is reported. The material under study consists of platelike graphite crystallites with basal crystallographic planes mostly oriented perpendicular to the substrate surface. An increase is revealed in the fraction of the graphite crystallites oriented perpendicular to the polarization plane. Laser light is found to cause significant anisotropy in diffuse scattering by the film surface. Experimental observations are explained by a model of anisotropic evaporation of graphite-like carbon material due to polarization dependence of the absorption and reflection coefficients for a rough surface.
