Abstract:

The results of experiments filamentation of terawatt femtosecond pulses of a Ti:Sapphire laser at atmospheric path length of 106 m using different spatial focus and power pulses are presented. The high efficiency control for the position and length of the field filamentation change the initial focus of the laser beam. The dependences of the length and position of filamentation on the initial degree of focus and power of the pulses, the number of filaments along the filamentation region are found. The obtained data on the length of the filamentation regionand the number of filaments with the results of earlier experiments and data of other authors were compared.

Keywords:
