摘要：
By considering the Gaussian spatial distribution of the intracavity photon density, we introduce the rate equations of a diode-pumped Nd:YVO4 laser doubly Q-switched by an acousto-optic modulator and a Cr4+:YAG saturable absorber. These rate equations are solved numerically, and the dependences of pulse width on incident pump power at different pulse repetition rates are obtained. It is shown that the pulse width is obviously compressed in contrast to a diode-pumped actively Q-switched laser with an acousto-optic modulator and the numerical solutions are in agreement with the experimental results performed by a diode-pumped doubly Q-switched Nd:YVO4 laser with acousto-optic Cr4+:YAG.
