摘　　要：报道了半导体泵浦Yb∶CaNb_2O_6晶体输出978 nm波长的激光器。泵浦模块采用了940 nm LD,在实现了Yb∶CaNb_2O_6薄盘激光器1.14 W的连续波输出的基础上,采用LBO非线性晶体进行内腔倍频实现了151 m W的489 nm连续二次谐波输出,在水平和垂直方向上的光束质量因子M^2分别为1.11和1.13。The diode - pumped Yb ： CaNb20 6 laser emitting at 978 nm is reported. The Yb ：CaNb20 6 thin - disk laserwith continuous wave（ cw） output power of 1. 14 W at 978 nm was realized by using 940nm LD pumping. Based onthis,intra - cavity second - harmonic generation（ SHG） in cw mode has also been demonstrated with a power of 151mW at 489 nm by using LiB3 0 5 （ LBO） nonlinear crystal. The beam quality factors M2 are respectively 1. 11 and 1. 13in horizontal direction and vertical direction.
