Destruction of the nano-size solid particles under femtosecond laser pulse action

The results of both analytical and numerical study of the optical damage of a solid nano-size particle, partly ionized by an ultra-short laser pulse (USLP) are presented. The comparison of the results that has been obtained analytically and numerically shows that the proposed method allows to describe the main features of nano-particle damage induced by Coulomb forces, that arise in solid due to the charge equilibrium distortion under USLP action. The kinetics of energy spectra of the spreading ions has been analyzed taking into account the Coulomb repulsive forces and the retarding processes that restrict ion motion inside the particle.
