Abstract :
An analytic model that takes into account dispersion, chirp, self-phase modulation, bandwidth limitation, frequency walkoff, and cavity length detuning is applied to lasers passively mode locked by two saturable absorbers-one fast and one slow. This general model predicts that the balance between slow gain and slow absorber affects pulse timing shifts and frequency changes. Such shifts limit the range of permitted intracavity dispersion
