Based on Au nanocages/SiO2 (Au-NCs/SiO2) as saturable absorber (SA), passively Q-switched Nd:YVO4 lasers with the output couplers (OCs) with the transmittance (T) of 4% and 10.8% were demonstrated, respectively. Q-switched pulse with the shortest pulse duration of 154.2 ns was achieved at T = 4% under the pump power of 2.11 W with the corresponding repetition rate of 280.0 kHz and average output power of 140.6 mW. While the maximum average output power of 150.2 mW was obtained at T = 10.8% under the pump power of 2.42 W, corresponding to the pulse width and repetition rate of 222.0 ns and 279.1 kHz.
