摘　　要：High-power cw green laser radiation is generated by intra-cavity frequency doubling of a diode-pumped Nd:GdVO_(4) laser with a MgO-doped periodically-poled LiNbO_(3)(MgO:PPLN)crystal at room temperature.An average power of 2.4 W at 0.53μm is obtained under the pump 15 W at 808 nm,corresponding to an overall optical-to-optical conversion efficiency of 16%.The M^(2) factor of the green beam is 3.90 and 1.34 for the horizontal and vertical direction,respectively.In addition,the power fluctuation is measured to be about±5%.
