摘要
报道了一种锁波长914nm共振抽运的Nd:YVO4/LBO腔内倍频的绿光激光器,利用锁波长914nm的半导体激光器作为抽运源,极大地提高了抽运的均匀性和抽运效率,降低了激光器的热效应,从而获得了高光束质量的532nm激光输出。当抽运功率为18W,调制频率为130kHz时,获得了最高输出功率为6.7W的绿光,入射抽运光的光-光转换效率为37.2%,对应的吸收抽运光的光-光转换效率为60%。
Herein,we report an efficient wavelength-locked 914-nm laser diode in-band pumped intracavity frequency doubling green laser.In our experiment,a wavelength-locked 914-nm laser diode is used as the pumping source to realize good pump uniformity and efficiency and substantially reduce the thermal effect of the laser.A 532-nm laser output with high beam quality is obtained.At a pump power of 18Wand a repetition rate of 130kHz,the maximum power output of 6.7 W for green laser is obtained.For this pumping power,the conversion efficiency is 37.2%,which corresponds to a conversion efficiency of 60%for absorbed pumping.
