During propagation of high-power femtosecond laser pulse in air dynamic balance between Kerr self-focusing and laser
plasma defocusing results in high localization of the energy in a hundred microns region. Stable long laser filament
forms. For systems of atmospheric optics it is important to control high fluence of the filament. We investigated
numerically the influence of pulse duration and atmospheric aerosol particles scattering on energetic characteristics of
the filamented laser pulse. It was shown that in the conditions of pulse energy remaining the same increase of pulse
duration results in considerable increase of filament length and high-fluence energy transporting by pulse. It is
demonstrated that scattering on atmospheric aerosol particles causes high-fluence energy losses but doesn't prevent
further filament propagation.
