Abstract

The kinetic time-dependent Fokker-Planck type equation for conduction electron energy distribution function is solved for bulk semiconductors and dielectrics in the presence of source terms such as laser field absorption, impact ionization and non-radiative recombination. The numerically calculated electron distribution function, time dependent electron number density and electron temperature are substituted into an equation for the lattice temperature evolution.
