Abstract
Considering the influence of crystal thermal loss and the intracavity loss of frequency doubling process, the four-lever nonlinear rate equation of passively Q-switched yellow laser is given. The characteristics of pulse-width repetition and output average power versus the pump power are obtained through numerical solution. The theoretical analysis accords with the experimental results excellently.
