The intracavity photon density is assumed to be Gaussian spatial distributions and the nonlinear loss that is due to second-harmonic generation (SHG) to the photon-density equation is given under Gaussian spatial distributions in the rate equations for a diode-pumped passively Q-switched intracavity-frequency-doubling Nd:GdVO4/KTP laser with Cr4+:YAG saturable absorber. These space-dependent rate equations are solved numerically. The dependences of pulse width, pulse repetition rate, single-pulse energy and peak power on incident pump power are obtained for the generated-green-laser pulses. In the experiment, a diode-pumped passively Q-switched intracavity-frequency-doubling Nd:GdVO4/KTP laser with Cr4+:YAG saturable absorber is realized and the experimental results are consistent with the numerical solutions.
