Computer simulations are carried out with the theoretical model presented in the previous paper for pulsed active-passive mode-locked Nd-glass and Nd : YAG lasers. The dependences of some characters of active-passive mode-locked lasers, such as mode-locking threshold, output stability, pulse width, pulse asymmetry, on modulation depth and detuning of the active modulator, concentration and relaxation time of the satura-ble dye, are given by the simulation calculations. The theoretical results are qualitatively in good agreement with experiments. Some experimental observations are explained. Thereby the physical processes involved in active-passive mode-locking are understood more deeply.
