Abstract

Summary form only given. Intense ultrashort IR laser pulses propagating through atmosphere undergo important changes in their spatial and spectral characteristics. They self-organize in the form of narrow filaments with high peak intensity, which persist over exceptional long distances. This spectacular effect is explained in terms of a dynamic competition between self-focusing and multi-photon ionization. We report evidence of a similar filamentation process in fused silica. Using femtosecond (160 fs) IR laser pulses from a Ti:sapphire laser in a converging beam geometry, we observe the formation of a microsize filament with nearly constant diameter over several mm.
