用提拉法生长了新型激光晶体5 at% Yb3+:YNbO4, 测量了它的吸收和光致发光光谱, 计算了它的吸收和发射截面, 并对其激光性能进行了评估. Yb3+:YNbO4的吸收半峰全宽为17 nm, 吸收峰位于933, 955, 974和1003 nm, 相应的吸收截面分别为0.731020, 1.8510-20, 0.8610-20和0.4410-20 cm2; 最大吸收截面值为Yb3+:YAG的两倍. 光致发光谱的发射带的中心位置处于1020 nm附近, 相应的半高宽为41 nm, 是Yb3+:YAG的3倍; Yb3+:YNbO4在955, 974, 1005, 1021和1030 nm处都有着较大的发射截面, 截面值分别为0.6910-20, 0.8610-20, 1.8110-20, 1.1110-20和0.5710-20 cm2, 最大发射截面值与Yb3+:YAG相当. Yb3+:YNbO4晶体的宽发射带有利于实现相应波长的超短脉冲和可调谐激光输出, 表明它是在这些领域非常有希望的全固态工作物质.

5 at%Yb3+:YNbO4 crystal is grown by Czochralski(CZ) method. Its transmission and emission spectra are measured. The absorption peaks are located at 933, 955, 974 and 1003 nm with their corresponding absorbtion cross section values 0.7310-20, 1.8510-20, 0.8610-20 and 0.4410-20 cm2; and the FWHM of 955 nm absorbtion peak is 17 nm. Its emission band centered at 1020 nm with the FWHM is 41 nm, which is over three times that of Yb3+:YAG crystal. The emission cross section values of 955, 974, 1005, 1021 and 1030 nm peaks are calculated to be 0.6910-20, 0.8610-20, 1.8110-20, 1.1110-20 and 0.5710-20 cm2, respectively, and the biggest one is comparable to that of Yb3+:YAG crystal. The laser parameters of 5 at% Yb3+:YNbO4 crystal are evaluated and the results suggest that it is a potential all-solid-state pumped laser crystal in tunable and ultrafast lasers field.-
