摘　　要：计算了Nd∶GdCOB晶体的相位匹配角。用Datachroom 5 0 0 0染料脉冲激光作为泵浦源 ,在Nd∶GdCOB晶体中实现了由 13 3 1.0nm到 665 .5nm的自倍频激光运转 ,阈值能量为 14.2mJ;当泵浦能量为 2 5mJ时 ,665 .5nm激光的输出能量为 0 .62mJ ,相应的转换效率为 2 .5 %。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%.
