Abstract

Starting with a nonlinear wave equation written in paraxial approximation, the time and space compression functions have been generalized to the case of a medium with the complex refractive index. The general dependencies allowing to analyze the time and space field distribution in the presence of single- and multiphoton resonance interaction and the nonlinear radiation refraction. By taking advantage of the formulae obtained the influence of the nonlinear interaction upon the change in the field distribution has been analyzed for some cases of practical interest.
