Multicolour nonlinearly bound chirped dissipative solitons.

Chirped dissipative solitons of the complex cubic-quintic nonlinear Ginzburg-Landau equation.

Approximate analytical chirped solitary pulse (chirped dissipative soliton) solutions of the one-dimensional complex cubic-quintic nonlinear Ginzburg-Landau equation are obtained. These solutions are stable and highly accurate under condition of domination of a normal dispersion over a spectral dissipation. The parametric space of the solitons is three-dimensional, that makes theirs to be easil...

Chirped Self-similar Pulse Propagation in Cubic-quintic Media

We consider nonlinear propagation of optical pulses in a cubic-quintic nonlinear medium wherein the pulse propagation is governed by the generalized nonlinear Schrödinger equation with varying dispersion, nonlinearity and gain/loss. Using the self-similar analysis, we present the generation of chirped bright solitons in the anomalous dispersion regime as well as the normal dispersion regime und...

Generation and scaling of highly-chirped dissipative solitons in an Yb-doped fiber laser

Generation of highly-chirped dissipative solitons (HCDS) in normal-dispersion cavity is treated now as a prospective technique to increase energy of femtosecond pulses delivered by an oscillator. Based on recently developed analytical model describing stable HCDS solutions, we have realized experimentally the regime of highly-chirped pulses in an Ybdoped fiber laser with passive mode locking vi...

Perturbed Dissipative Solitons: A Variational Approach

We adopt a variational technique to study the dynamics of perturbed dissipative solitons, whose evolution is governed by a Ginzburg–Landau equation (GLE). As a specific example of such solitons, we consider a silicon-based active waveguide in which free carriers are generated through twophoton absorption. In this case, dissipative solitons are perturbed by physical processes such as third-order...
