Abstract

The results of experiments to study the spatial characteristics of multiple filamentation gigawatt laser pulses in the glass are presented. It is shown that with increasing pulse power multiple filamentation region increases in length and diameter, the distribution of filaments within the region has a maximum value when the power > 10⁵ P_cr area filamentation takes the form of a hollow cone, the apex directed to the source of the laser radiation.
