The results of theoretical analysis of the response of solid nanoparticles on the dielectric surface to the intense ultrashort laser pulse (USLP) action are presented. The estimation of the ionization degree of nanoparticles with permanently changing charge on the composition, intensity and laser pulse duration has been carried out using a simple analytical model. The dynamics of non-thermal destruction of nanoparticles and associated changes in the substrate surface due to the implantation of ions emitted from nanoparticles has been studied using numerical simulation.
