Ultrashort Soliton in passively mode-locked Fiber laser

Based on the Maxwell-Bloch formalism, operation of a passively mode-locked fiber laser is numerically investigated. It is found that even without the Ginzburg-Landau Equation (GLE) approximation stable solitary waves can still be obtained in the laser due to the cavity pulse peak clamping effect. We further show that the effects of coherence play a significant role in determining the parameters of the formed solitary pulses.
