Paper Abstract

We investigate a novel type of solitons - chirped solitons- in the various problems of photonics which deals with the femtosecond laser pulse propagation in the media with nonlinear non-stationary absorption. This type of solitons is characterized by the complicated pulse chirp and allows self-similar propagation of laser radiation at the distances up to several dispersion lengths. In our analytical considerations, we develop approximate formulas which describe the nonlinear chip and the soliton shape. We confirm our analytical results by the numerical simulation of the considered problems: femtosecond laser pulse propagation in the media with nanorods or in the fused silica with taking into account non-stationary multi-photon absorption, nonlinear refraction, nanorods melting.
