Аннотация: The results of experiments on the study of spatial characteristics of the multiple filamentation domain of GW Ti:Sapphire laser pulses in glass are presented. The dependences of the coordinates of the beginning, end, and diameter of the multiple filamentation domain (MFD) vs the laser pulse energy are derived. It is found that whenПоказать полностьюthe average intensity in the beam attains certain values, MFD is formed near the illuminated side of the glass sample. When the beam intensity attains a threshold, the secondary MFD is formed; its spatial characteristics depend on the pulse-periodic irradiation exposure time. The diameter of the secondary MFD and coordinates of its beginning depend on the exposure time. The spatial characteristics of the primary MFD were independent of the exposure time during the experiments. © 2017, Pleiades Publishing, Ltd.
