Nonlinear Dynamics of Multiple Scattering of Intense Radiation in Randomly Inhomogeneous Media

摘要

Nonlinear effects of multiple scattering of intense radiation in randomly inhomogeneous media are studied. A family of solitary solutions of Schrdinger equations are obtained that give a self-similar description of the evolution of scattered pulses of electromagnetic radiation, and the asymptotics of the solutions are found. The possibility of a sharp compression of pulses propagating in scattering dispersion media is established and is interpreted as wave collapse. Results of the numerical simulation of the processes of self-action of intense radiation propagating in nonlinear dispersion media are presented.
