Аннотация:Using a femtosecond Ti:Sapphire laser we experimentally
and numerically simulated in the laboratory vertical
propagation and filamentation in the atmosphere for up to
10 km by changing the pressure in a gas cell. Filament diameter
increased at reduced pressures in air. This is a manifestation of
the invariance of intensity clamping. Filaments produced at low
pressures corresponding to higher altitudes were shown to reveal
excellent transport properties due to the wide low-density
plasma column extended homogeneously over long propagation
distances.
