30 January 1997 Stability conditions for soliton fiber lasers with nonlinear gain
Author Affiliations +
The steady-state soliton parameters are studied both for anomalous and normal dispersion regimes of a fiber laser, taking into account the effects of fiber dispersion and nonlinearity, linear gain and gain dispersion, nonlinear gain and two-photon absorption. It is shown that both the soliton chirp and width are significantly larger for normal than for anomalous dispersion. The existence of singularities for the soliton width and amplitude are revealed for both dispersion regimes. In the case of anomalous dispersion, the soliton perturbation theory and the phase-plane formalism are used to investigate the stability of the steady-state solution.
