摘要：

The intracavity photon density and the initial population-inversion density are assumed to be Gaussian spatial distributions in the rate equations of a laser-diode end-pumped passively Q-switched intracavity-frequency-doubling Nd:YVO4/KTP laser with Cr4+:YAG saturable absorber. These space-dependent rate equations are solved numerically. In the experiment, a laser-diode end-pumped passively Q-switched Nd:YVO4/KTP laser with Cr4+:YAG saturable absorber is realized. The dependences of pulse width, pulse repetition rate, single-pulse energy and peak power on incident pump power are measured for the generated-green-light pulses, and the experimental results are consistent with the numerical solutions.
