We demonstrate a laser-diode(LD)pumped actively Q-switched laser with Nd:Sc0.2Y0.8Si O5(Nd:SYSO)crystal for the first time.A stable actively Q-switched laser is obtained at dual wavelengths of 1 075.2 nm and 1 078.2 nm.The maximum average output power of 720 m W is obtained at the repetition rate of 15 k Hz under the pump power of8.7 W.The minimum pulse width of 58 ns is obtained at the repetition rate of 5 k Hz under the pump power of 8.7 W,corresponding to the peak power of 1.9 k W and the pulse energy of 112μJ.
