The present review concentrates on the excimer laser pulse laser
modification of metal nanoparticles synthesized by ion implantation in amorphous
dielectrics such as silicate glasses. One of the main features of composite samples
prepared by the low ion implantation is the growth of metal particles with a very
wide size distribution in the depth from the irradiated substrate surface. Pulsed
laser irradiation makes it possible to modify this 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 silver
nanoparticles, and some long range dissolution of silver in the glass. This is
particularly promising for the development of the technology of obtaining nonlinear
optical materials. To control the parameters of the obtained layers a method based
on an analysis of the optical reflection spectra measured on the side of the
implanted and rear surfaces of glass is applied. Also, the factors influencing the
experiment are discussed and the optical extinction spectra of the nanoparticles in
the glass are modeled using the Mie theory.
