Paper Abstract

The theory based on energy-band, which tracks free-electron in optical dielectrics, is established to describe laser-dielectrics-interaction process. The relations between damage threshold and laser frequency, band gap are investigated. Numerical analysis on SiO2-TiO2 stacks has been done. One-dimensional finite difference method is used to solve kinetic equation. The results show that the damage threshold of pure material decreases with the increase of laser frequency. And it increases with the increase of band gap.
