Abstract

Intense ultrashort IR laser pulses propagating through atmosphere self-organize in the form of narrow filaments with high peak intensity, which persist over exceptional long distances [1]. This spectacular effect is explained in terms of a dynamic competition between self-focusing and multi-photon ionization (MPI). Recent numerical simulations [2] displayed evidence that, analogous pulse filamentation can appear in transparent solids as well. Here we report the first experimental evidence of this filamentation process in fused silica.
