Abstract
The evolution of dissipative solitons (DSs) in passively mode-locked erbium-doped fiber lasers with net normal-dispersion has been investigated numerically. Numerical results show that the net cavity dispersion (Dnet), the output coupling ratio (η), the bandwidth of the spectral filter (SFBW) and the gain saturation energy of the Er-doped fiber (Esat) all affect the pulse energy, profile and stability of the DSs. It was found that by adding a segment of dispersion compensation fiber (DCF) to build a highly positive dispersion regime, combining the actions of an amplitude modulator and a spectral filter, and choosing an optimal output coupling ratio, stable, high-energy dissipative solitons could be obtained.
