Abstract

The general form of the kinetic equation for the filament number density with allowance for effects of their creation and decay is formulated—a nonlinear diffusion equation. The equation includes phenomenological parameters obtained by direct numerical simulation of the propagation of a high-power femtosecond laser pulse based on the stationary nonlinear Schröbinger equation for a number of limiting special cases.
