Abstract:

Multifilamentation of a high-power femtosecond laser pulse is investigated numerically based on the model of phase screens emulating the wide-band atmospheric turbulence. As an example, a single phase screen is used to analyze the stochastic process of a successive filamentation and statistical characteristics of these filaments. It is shown that the probability of observing large number of filaments increases with distance. It has been established by use of the Monte Carlo technique that statistical characteristics of the filament bunch are strongly dependent on the structure constant C2,n, while the dependence on the inner scale of turbulence ll0 is rather weak.
