Abstract

We report on experimental and numerical investigations of femtosecond pulse propagation locally disturbed by the turbulent flow field of a hot-air blower. The experiments show that turbulence may shorten the collapse/filamentation distance and induce the onset of multiple filaments. This is supported by numerical simulations indicating that the high spatial frequency part of the turbulence spectrum plays a significant role.
