Travelling wave model for a resonator containing a saturable absorber

Summary form only given. For low outcoupling and nonsaturable losses, the traveling-wave model agrees exactly with the rate equation model (REM). Comparing simulated pulses from both models for a case with high outcoupling losses for the TWM, the outcoupling was from the Q-switch side of the resonator. In this case the peak power obtained from the traveling-wave model is about 20% higher than that predicted with the rate equation model.
