摘要：
A compact diode-pumped doubly Q-switched extracavity frequency-doubled Nd:YVO4/KTP green-pulse laser was demonstrated, using both an acoustic-optic (AO) modulator and a GaAs saturable absorber in a simple flat-flat cavity. The green laser can generate a more symmetric and shorter pulse when compared with purely AO and passively Q-switched lasers. A peak power of 7.54 kW with the corresponding pulse width of 3.2 ns has been achieved with the incident pump power of 7.76 W and f(p) = 15 kHz. A reasonable analysis about the experimental results has been given.
