Spatio-temporal control of femtosecond laser pulse filamentation in the atmosphere

Abstract

Atmospheric turbulence influence on stochastic filamentation of the chirped femtosecond laser pulses in the kilometerrange propagation is analyzed. The problem of the chirped pulse parameters optimization is discussed. An effective semi-analytical method is suggested to investigate chirped pulse propagation and filamentation over kilometer range distances in the turbulent atmosphere.
