▎ 摘　　要

We demonstrate a passively Q-switched c-cut Nd:YVO4 laser based on graphene-oxide (GO) as a saturable absorber (SA). The Q-switched laser has a low pump threshold of 1.5 W. The pulse repetition rate can be widely changed from 62 kHz to 386 kHz by increasing the pump power from 1.5W to 3 W. The minimum pulse width is 246 ns and the maximum average output power is 514 mW.
