We consider the statistics of light amplitude fluctuations for the propagation of a laser beam subjected to multiple filamentation in an amplified Kerr media, with both linear and nonlinear dissipation. Dissipation arrests the catastrophic collapse of filaments, causing their disintegration into almost linear waves. These waves form a nearly Gaussian random field that seeds new filaments. For small amplitudes the probability density function (PDF) of light amplitude is close to Gaussian, while…

Strong collapse turbulence in a quintic nonlinear Schrödinger equation.

This work considers the quintic one-dimensional nonlinear Schrödinger equation with forcing and both linear and nonlinear dissipation, and defines the powerlike tail of the PDF for large-amplitude fluctuations, i.e., the intermittency of strong turbulence.

It is proved that the intensity fluctuations at large propagation distances possess a Gaussian probability density function and quantitative criteria for realizing the Gaussian statistics depending on the laser propagation distance, laser beam waist, laser frequency, and turbulence strength are established.
