Paper Abstract

The robustness and recoverability of the high-power femtosecond laser pulse filament in the presence of atmospheric aerosol scattering layer was studied by means of computer simulation. The obtained patterns of fluence and electron density in a laser filament demonstrate that these parameters acquire a stochastic character inside the aerosol layer and recover on leaving it. Filament energy decreases with distance inside the layer because of the water particles scattering and after the layer because of the amplitude-phase perturbations induced by aerosol particles. The equivalence of nonlinear aerosol medium and linear damping medium with equal to disperse dissipations was investigated.
