摘要：
In this paper, we report a laser diode-end-pumped Nd:YVO4 laser, doubly Q-switched by an acousto-optic (AO) Q-switch and a Cr4+:YAG saturable absorber. At the pump power of 6.1 W and the pulse repetition rate of 125 kHz, the shortest pulse width of 7 ns is achieved. When the Cr4+:YAG saturable absorber is removed from the resonator, the corresponding pulse width is 13 ns. In contrast to an AO Q-switched laser, it is shown that the pulse width is obviously compressed in a doubly Q-switched laser with AO and Cr4+:YAG.
