Abstract

In this paper we describe the interaction of an intense laser beam with metallic nanoparticles embedded in glass. Energy deposition in the metal is calculated on the basis of Mie's scattering theory, using an accurate model for the dielectric function which involves interband transitions. As is shown by two-temperature modeling of the laser-heated metal, nonequilibrium thermodynamics must be used to describe such systems, even in the nanosecond laser pulse range. Taking into account the particle cooling process by heat diffusion in the glass matrix, the model provides a useful tool for the understanding of laser damage initiation by metallic nanoinclusions.
