Abstract :
The behaviour of a composite laser is simulated numerically but the model for the main cavity explicitly uses synchronous pumping as the mode-locking mechanism of the main cavity. This brings the model closer to the actual experimental conditions. The use of an optical fibre (with both normal and anomalous dispersion) in the control cavity can be simulated by numerical solutions of the nonlinear Schrodinger (NLS) equation. The behaviour of a semiconductor diode amplifier used as the external mode-locking element may be modelled as a mapping from the input to the output pulse of the control cavity which incorporates, in a simple way, the effect of saturable amplification
