The results of experimental and theoretical study of the self-action of femtosecond optical vortices in the region of anomalous group velocity dispersion in fused silica and fluorides are presented. Multiple filamentation of an axially asymmetric ann

This paper presents a retrospective analysis of the development of notions in nonlinear optics: from beam self-focusing and pulse filamentation to light bullets – wave packets extremely compressed in space and time during laser light propagation in

Specific features of the anti-Stokes band of the light bullet supercontinuum spectrum under filamentation of 1900-nm femtosecond pulses, focused by an axicon in fused silica and calcium fluoride, have been experimentally, numerically, and analyticall

The formation of annular light bullets during the filamentation of femtosecond optical vortices in a LiF crystal under conditions of anomalous group velocity dispersion is considered. Features of the spatiotemporal dynamics of pulses are described. Q

We analyze numerically the femtosecond filamentation of a vortex beam with the topological charge m = 1 at wavelength λ0 = 1800 nm in fused silica under anomalous group velocity dispersion conditions. We show that, as a pulse with a fivefold excess

The results are presented from investigating the light bullet spectrum in the filamentation of femtosecond pulses in calcium fluoride. A physical scenario is proposed for the generation of the anti-Stokes wing of the supercontinuum during the formati

Filamentation of femtosecond optical vortex at central wavelengths of 1800 nm and higher in fused silica and fluorides was experimentally and numerically studied. The features of broadening of frequency and frequency-angular spectra are considered.

In the present work we investigated experimentally and numerically the formation and self-reconstruction after an air gap of extremely compressed wave packet — “light bullet” (LB) in process of Near-IR and Mid-IR femtosecond filamentation. We s
We have studied the penetration of the extremely compressed wave packet—“light bullet” (LB)—through an air gap upon femtosecond single-pulse mid-IR filamentation in LiF. Applying the laser coloration method and performing numerical simulation
