The filamentation of femtosecond laser pulses and filament-induced self-writing of a
permanent waveguide are observed in As 4 Ge 30 S 66 chalcogenide glass. The radial …

Detailed picture of continuous shape evolution of femtosecond laser pulse has been
recorded directly in the process of filament formation in fused silica using time-resolved …

We investigate femtosecond pulse propagation in a medium containing nanorods, taking
into account the dependence of two-photon absorption from the aspect ratio of nanorods …

The full description of the evolution of light during its nonlinear propagation represents a
valuable help to the complete understanding of important nonlinear phenomena such as …

We study experimentally and numerically the spatiotemporal dynamics of the multiple
filament arrays excited by self-focusing of intense elliptical laser beams in fused silica. Our …

We demonstrate the possibility of decelerating chirped soliton formation at femtosecond
pulse propagation in a medium with gold nanoparticles. We take into account the …
