Paper Abstract

We report the results of theoretical study of damage, induced by Coulomb forces, in (a) solid nanoparticles, and (b) the surface of solid dielectric, ionized by ultrashort laser pulses (USLP). The basic assumption of proposed model is that the damage occurs due to the laser-induced disturbance of charge equilibrium in solid with the further electron emission from irradiated area. When electrons outflow from crystal, the non-compensated positive charge creates a strong electrostatic field, causing the movement of the charged sites and micro- and/or macro- destruction of the condensed matter.
