Abstract

The results of experimental studies of postfilamentation channels controlled by the track length of 150 meters for collimated beams of different diameters. It is shown that the divergence of the laser beam after the filamentation area is much greater than the divergence postfilamentation channels. It is shown that at distances from the end of the field filamentation, significantly exceeding the length of the field filamentation, postfilamentation channels contain sufficient intensity to generate multiple filamentation in the optical elements and enables us to provide a functional effect on the optical elements of the matrix.
