A diode-pumped Nd : YVO4 laser passively Q switched with GaAs is studied theoretically and experimentally. We have demonstrated the in uence of single-photon absorption, two-photon absorption and free-carrier absorption in GaAs on the Q-switched pulse characteristics. The pulse proΓΏle, pulse energy
Passive Q-switching of a laser-diode-pumped intracavity-frequency-doubling Nd:NYW/KTP laser has been realized with GaAs semiconductor saturable absorber. The dependence of pulse repetition rate, pulse energy, and pulse width on incident pump power are measured. The coupled rate equations are used to
