Paper Abstract

We applied a Monte Carlo simulation for studies of single-shot laser-induced breakdown in pure transparent dielectrics for the case when the photon energy is close to or exceeds mean electron energy. Avalanche ionization rate dependence on intensity was obtained by solving both the kinetic Fokker-Planck type equation and the quantum kinetic equation. Threshold scaling with pulse width was obtained in the range from 3 ps to 30 ns for several values of laser frequency and initial lattice temperature. Lattice heating influence (during the laser pulse action) on avalanche ionization rate was studied.
