Abstract

 

From Maxwell equations we deduced the combined equations describing the evolution of overlarge space-time
spectra of light waves in homogeneous isotropic dielectric medium with arbitrary dependence of linear index of
refraction and instantaneous cubical nonlinearity. We’ve got analytical iterative solution of the acquired
combined equations. Solutions of the linearized combined equations are illustrated by the results of numerical
simulation of femtosecond wave packet of a few optical oscillations propagation in a fused silica.

Keywords:   nonparaxiality, femtosecond pulse, space-time spectra, cubical nonlinearity, overlarge spectra, iterative solution, nearby infrared range, optical glass, dispersion broadening, diffraction broadening.
