Rate equation simulation of a synchronously pumped dye laser

A simple rate equation model of a standing wave synchronously pumped dye laser yields output pulses which agree qualitatively and quantitatively with recent experimental observations. The shape, amplitude and temporal position of the simulated pulse varies dramatically, not only with cavity length detuning, but also with the gain to loss ratio. Features of pulse formation and stability are predicted which are precluded by the steady-state assumption present in most other models.
