Abstract: The phase matching angle of Nd:GdCOB is calculated.Using Datachroom-5000 pulsed dye laser as pump source,we have realized the self-frequency-doubling laser from 1331.0nm to 665.5nm in Nd:GdCOB crystal. The experiment results show that the threshold energy for the crystal is 14.2mJ;when the pump energy is 25mJ,the output 665.5nm laser energy is 0.62mJ and the corresponding conversion efficiency is 2.5%.
