The 885 nm direct pumping directly into the 4F3/2emitting level of Nd3+is applied on an Nd:Lu0.15-Y0.85VO4crystal. The maximum output power of 2.8 W for continuous wave (CW) operation is obtained. For Q-switched operation, the maximum average output power is 1.2 W with pulse repetition of 23.69 kHz and pulse width of 35 ns at the pump power of 27.9 W. The high-quality fundamental transverse mode can be observed owing to the reduction of thermal effect for Nd:Lu0.15-Y0.85VO4crystal by 885 nm direct pumping.
