摘要：

Passive modelocking tends to produce secant hyperbolic pulses with exponential wings in the time domain. The recent observation of gaussian pulse wings could be explained if one postulates a saturable absorber mechanism that simulates a logarithmic dependence of absorption upon intensity. Two models are investigated: two conventional saturable absorbers and two KLM equivalent absorbers. The analysis shows ways for pulse-shaping of modelocked pulses away from the standard sech shape, not only in producing gaussians, but some other pulse-shapes.
