摘　　要：采用助熔剂法生长Yb0.05:Gd0.20Y0.75Al3(BO3)4(Yb:GdYAB)和Yb0.05:Y0.95Al3(BO3)4(Yb:YAB)晶体。比较这两种晶体的室温吸收光谱、荧光光谱、荧光寿命及热膨胀、比热等热学性质。结果表明,Yb0.05:Gd0.20Y0.75Al3(BO3)4晶体是一种优秀的激光自倍频晶体,可以实现自倍频激光输出,并且具有宽的可调谐范围。Yb0.05：Gd0.20Y0.75Al3（BO3）4（Yb：GdYAB） and Yb0.05：Y0.95Al3（BO3）4（Yb：YAB） crystals have been grown using the flux method. Their absorption and fluorescence spectra were measured at room temperature and important spectroscopic parameters were calculated. Through the comparison of spectroscopic parameters for the Yb：GdYAB and Yb：YAB, it is indicated that the 5 at% Yb＇GdYAB crystal is an excellent self-frequency-doubling laser crystal and potential candidate for compact, efficient thin chip lasers.
