摘　　要：We describe a Q-switched Er：GdVO4 laser resonantly pumped by a MgO-doped periodically poled LiNbO3 optical parametric oscillator （MgO： PPLN OPO） at 1 536 nm. In continuous-wave lasing, the maximum output power is 1.14 W with an incident pump power of 4.7 W and a slope efficiency of 27%. In Q-switched operation, 1.1 mJ of output pulse energy is achieved at 200 Hz. The upper-state lifetime at different pulse repetition frequencies is also calculated.We describe a Q-switched Er：GdVO4 laser resonantly pumped by a MgO-doped periodically poled LiNbO3 optical parametric oscillator （MgO： PPLN OPO） at 1 536 nm.
