Abstract
The results of theoretical investigation of processes resulting from disturbance of charge equilibrium in a solid nanoparticle, induced by fast ionization under high-intensity ultra-short laser pulse action are presented. Analytical and numerical methods were used to study time evolution of space and energy distributions of moving ions during their spreading away from the particle for various sizes and shapes of the particle as well as various degrees of ionization of its material. The final aim of the presented study is to analyze the influence of the disturbance of charge equilibrium induced by high-intensity ultra-short laser pulses in a solid on parameters of laser-induced damage of the material, and the regularities of the atoms and ions motion of the media in damage area under the action of local laser-induced Coulomb potential.
