Abstract:

The theoretical aspects of self-focusing and filamentation of high-power pulsed CO2-laser radiation with the carrier wavelength 10.6 μm in air are considered. The frequency-differential molecular absorption of atmospheric air is included in the theoretical model. It is shown that in the conditions of pulse self-phase modulation, the super-broad pulse spectrum is strongly affected by atmospheric absorption that destabilizes the filamentation process and leads to the considerable reducing of the plasma channel length formed in the beam wake.

Keywords:

ultra-short laser radiation, self-focusing, filamentation, ionization, laser plasma
