Abstract
A model is presented for the pulse-shaping dynamics in an actively mod e-locked laser in which the losses are AM modulated at two harmonic fr equencies differing by the cavity fundamental mode spacing and is appl ied to the case of third and fourth harmonics. Coupling to eight side modes is demonstrated. Computer simulations are implemented for a line ar resonator which show the effects of modulation and gain for differe nt initial conditions of field-amplitude and phases.
