Abstract

Recent results on the interaction of high power laser pulses with various dielectric materials containing metal nanoparticles are reviewed. The excimer laser pulse modification of silver nanoparticles synthesized by ion implantation in soda-lime silicate glasses are considered. One of features of composite samples prepared by the low energy ion implantation is the growth of metal particles with a wide size distribution in the thin depth from the irradiated substrate surface. Pulsed laser irradiation makes it possible to modify such composite layer, improving the uniformity in the size distribution of the nanoparticles. Changes induced by pulsed laser exposure suggest there are both reductions in average size of the metal nanoparticles, and some long-range dissolution of metal atoms in the matrix. Experimental data on laser modification are explained by melting of the nanoparticles in the dielectric matrix.
