Growth and Spectral Properties of Yb3+-doped Ba3Gd(BO3)3 Crystal

摘要

Crystal of Yb3+-doped Ba3Gd(BO3)3 has been grown by the Czochralski method.The spectroscopic characterizations have been investigated at room temperature. The Yb3+: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 cm2 at 976 nm and 0.97×10-21 cm2 at 1040 nm, respectively. The fluorescence lifetime is 2.84 ms.
