Propagation of a High-Power Femtosecond Pulse Filament through a Layer of Aerosol

The propagation of a filament created by a strong femtosecond pulse through a layer of aerosol is studied. It is shown that the filament is stable with respect to perturbations caused by scattering from particles and restores its regular axial symmetry after the aerosol layer. The integral characteristics of the filament are analyzed. The possibility of replacing the disperse nonlinear medium with the continuous one is discussed.
