摘要：
The Nd3+-doped Ba3Gd2(BO3)(4) crystal with high optical quality and large size is reported in this paper. The growing processes and characteristics of Nd3+:Ba3Gd2(BO3)(4) crystal are discussed. The absorption and luminescence spectra of Nd3+ in Ba3Gd2(BO3)(4) crystal were measured at room temperature. The luminescence decay curve in correspondence with the F-4(3/2) -> I-4(11/2) transition centered at 1062 nm was also measured. The JO intensity parameters Omega(t) (t = 2, 4, 6) were calculated to be Omega(2) = 1.263, Omega(4) = 2.496, Omega(6) = 3.606. The radiative lifetime tau(r) and fluorescence lifetime tau(f) are 317.771 and 115 mu(s) respectively, and the fluorescence quantum efficiency is 37.1%.
