Paper Abstract

In present paper we enhance the model of polarization response in field of extremely short pulse by a pseudoclassical description of multiphoton ionization. The system of material equations now includes a part related to a ionization nonlinearity of the optical material. We also obtain a new wave equation, which describes extremely short pulse propagation in tnmsparent dielectric when electromagnetic field intensity values approach to a boundary of dielectric destruction beginning. The equation is used for modeling computations, numerical analysis of pulse propagation. Also new expressions for media refraction index are derived from the equation.
