Femtosecond Laser Pulse Filamentation under Anomalous Dispersion in Fused Silica |

| Abstract: | In this paper, it is reported that the results of investigation of femtosecond laser pulse filamentation in fused silica by varying the wavelength ranging from 800 to 2300 nm. It is shown that in the case of the anomalous group-velocity dispersion, a sequence of ＇light bullets＇ with a high spatial and temporal localization of the light field is formed along the filament. There is a united relation between the formed and propagated light bullets with the formation of an isolated anti-Stokes wing of the supercontinuum spectrum. |
