Abstract

The results of experimental research of the filamentation of femtosecond laser pulses using a bimorph deformable mirror, which allows controlling the position of the filamentation domain determining localization of filaments and high-intensity channels in the beam cross section. The introduction of distortions into the amplitude profile of the beam with using masks showed the inability to control the number and position of filaments in the beam cross section.
