Abstract :
A numerical model for the evolution of a pulse inside the cavity of a laser containing a quantum well absorber is introduced. The model confirms the optical Stark effect as the mechanism behind the mode-locking of these pulses. The evolution reaches a steady state when a gain bandwidth filter is introduced to balance this effect.
