We present here a model of a QCW diode pumped passively Q-switched laser. Both numerical and approximate analytical solutions to the laser rate equations are described for a range of parameter values including output coupler reflectivity, pump power and doping levels within the saturable absorber. In particular, the conditions that result in a single output pulse per pump pulse are investigated. Pulse duration and pulse energy are also calculated. The example case of a QCW diode pumped Cr,Nd:YAG crystal is considered. The model is verified by comparison to experimental results.
