High-power cw green laser radiation is generated by intra-cavity frequency doubling of a diode-pumped Nd∶GdVO4 laser with a MgO-doped periodically-poled LiNbO3 (MgO∶PPLN) crystal at room temperature.An average power of 2.4 W at 0.53 μm is obtained under the pump 15 W at 808nm,corresponding to an overall optical-to-optical conversion efficiency of 16％.The M2 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％.
