Abstract
The results of experiments to study the spatial characteristics of the field of multiple filamentation (FMF) gigawatt pulse Ti:Sapphire laser in the glass. The dependences of the coordinates of the beginning and end of the FMF, the diameter of the laser pulse energy were received. It was found that when a certain average intensity values in the beam FMF has formed around the illuminated faces of the glass sample. It is shown that when the threshold intensity of the beam is formed by a secondary area of multiple filamentation, the spatial characteristics of which depend on the time of exposure to repetitively pulsed laser radiation. The dependence of the diameter of the secondary FMF and coordinates its start from the effects of time. The time dependence of the impact of the spatial characteristics of the primary field of multiple filamentation experiments absent.
