Abstract:

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 the beam cross section, and forming long (> 100 m) high-intensity (1011 – 1012 W/cm2) weakly diverging plasma-free channels.

Keywords:

femtosecond laser pulse, filamentation, deformable mirror
