摘要
Crystal of Yb^3＋-doped Ba3Gd（BO3）3 has been grown by the Czochralski method. The spectroscopic characterizations have been investigated at room temperature. The Yb^3＋：Ba3Gd（BO3）3 crystal exhibits broad absorption at 976 nm with FWHM of 7 nm and large overall spitting of ^2F7/2 manifold （823 cm^-1）. The absorption and emission cross sections are 5.09×10^-21 cm^2 at 976 nm and 0.97×10^-21 cm^2 at 1040 nm, respectively. The fluorescence lifetime is 2.84 ms.
