Abstract

A system of equations is obtained that describe the dynamic parameters of super-Gaussian pulses propagating in an isotopic dielectric. It is shown that a nonlinearity dispersion can suppress the formation of the nonlinear focus. An expression is derived for the critical signal power at which self-focusing can still be compensated for by diffraction divergence.
