Abstract

We have observed self-guiding of a single femtosecond visible laser pulse in the bulk of fused silica. The filament length and diameter versus pulse energy have been measured. Velocity of ions flying out from the plasma channel was determined with the use of time-of-flight measurements. The laser-induced micromodification in the bulk of the fused silica has discrete structure and is close to the filament form.
