Аннотация

The formation of light bullets and the generation of a broadband supercontinuum with the minimum wavelength in the UV region are observed upon the filamentation of a femtosecond laser pulse in transparent dielectrics under conditions of an anomalous dispersion of group velocity. The duration of a light bullet, measured via laser coloration, is around one period of the light field’s oscillation, and its diameter is less than 10 μm. Numerically calculated parameters of the light bullet are in good agreement with experimentally measured values.
