The Effect of Phase Aberrations on the Position and Length of the Filamentation Domain

The results of experimental and theoretical studies of femtosecond laser pulse filamentation with use of a bimorph deformable mirror are presented. The mirror allows controlling the position of the filamentation domain throughout a model path due to phase distortions of different parts of a laser beam, determining localization of filaments and high-intensity channels in a beam cross section, and forming long (>100 m) high-intensity (1011–1012 W/cm2) weakly diverging plasma-free channels.
