Paper Abstract

The goal of the work was the experimental study of femtosecond filamentation laser pulses using a bimorph deformable mirror (DM). Phase distortions of different parts of the laser beam make it possible to control the position of the filamentation domain along the entire length of the model path. The use of a bimorph deformable mirror makes it possible to determine the localization of filaments and high-intensity channels in the cross-section of the beam. The mode of formation of long (> 100 m) high-intensity (1011-1012 W/cm2 ) weakly converging non-filamentary channels was detected.
