采用大功率二极管侧面抽运Nd:YAG晶体,在含望远系统的双棒串接四镜折叠腔结构下,利用双声光开关调Q及三硼酸锂(LBO)晶体内腔倍频的方式,通过谐振腔和倍频晶体参数优化设计,获得了重复频率为10 kHz,波长为659.5 nm,平均功率大于105 W的高功率红光激光输出,光-光转换效率达6.6%。 The Nd: YAG crystal was pumped by the side of high power diode. Under the double-rod cascade four-mirror folding cavity structure with the telescopic system, the double-acousto-optic switch was used to tune Q and the intracavity doubler of lithium boronic acid (LBO) By optimizing the parameters of resonant cavity and frequency doubling crystal, a high power red laser output with a repetition frequency of 10 kHz, a wavelength of 659.5 nm and an average power of more than 105 W was obtained. The light-to-light conversion efficiency was 6.6%.
