Paper Abstract

We consider an affection of femtosecond laser pulse on nonlinear medium in the framework of thin layer and thick layer of medium. Laser pulse propagation is described by 1D non-stationary Maxwell equations together with nonlinear polarization equation. We compare results of mathematical modeling based on two types of description of polarization. The first of them uses a Duffing's approach. The second is based on application of electron-nuclear interaction potential with saturation. We investigate also an influence of laser pulse duration on a shift of spectrum polarization frequency of maximum amplitude.
