Abstract

The multiple filamentation of collimated beams delivered by the teramobile laser was investigated for power upto several terawatts (TW). Long-range filaments were initiated by the most intense fluctuations of the input beam and persisted over several tens of meters. The small-scale spots arised and recurred rapidly in the diffraction plane in agreement with the optically turbulent light guides. The evolution of the filament patterns were qualitatively reproduced by an averaged-in-time-dimensional model derived from the propagation equations for ultrashort pulses.
