  • Abstract
    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 laser-diode end-pumped passively Q-switched intracavity-frequency-doubling Nd:GdVO4/KTP laser with a GaAs saturable absorber. These space-dependent rate equations are solved numerically. The dependences of pulsewidth, 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 laser-diode end-pumped passively Q-switched intracavity-frequency-doubling Nd:GdVO4/KTP laser with a GaAs saturable absorber is realized, and the experimental results are consistent with the numerical solutions.
