摘要: 计算了Nd:GdCOB晶体的相位匹配角。用Datachroom-5000染料脉冲激光作为泵浦源,在Nd:GdCOB晶体中实现了由1331.0nm到665.5nm的自倍频激光运转,阈值能量为14.2mJ;当泵浦能量为25mJ时,665.5nm激光的输出能量为0.62mJ,相应的转换效率为2.5%。

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%.
