Abstract

We present the results of the turbulent layer influence on the characteristics of the filamentation domain at the path beginning for the beams with a diameter of 2.5 and 5 cm. Addition of turbulence results in the fact that the beginning of the multiple filamentation domain (MFD) to the source coming closer. Decreasing of the distance to the beginning and end of the MFR in the presence of turbulence is inappreciable (<10%). The turbulent layer formed at the beginning of the path leads to a multiple increase in the number of the intense channels (~ 10¹¹-10¹² W/cm2) with a length >100 m.
