摘要：

A modified equation describing the laser field in a passively mode-locked laser is presented. This model includes a fast saturable absorber which is bleached only over a limited intensity-range, as in an additive pulse mode-locked (APM) laser. Dynamic stability is analyzed in the near-soliton limit, and it is shown that the fifth-order saturable absorber term plays a key role in stabilization. The model is compatible with the experimental observation of per-pass nonlinear phase shifts on the order of pi/2 radians in APM lasers. Finally, approximate and exact solutions are obtained.
