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

摘要

Atmospheric turbulence influence on stochastic filamentation of the chirped femtosecond laser pulses in the kilometer-range 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.
