N2 - Trivalent praseodymium ions were added in bismuth-containing tellurite (LKBBT) and gallate (LKBBG) glasses to develop potential oxide glass amplifier medium operating at 1.3 μ m. Based on optical absorptions, three phenomenological Judd-Ofelt parameters Ω2, Ω4 and Ω6 of Pr3 + have been derived to be 4.14 × 10- 20, 6.88 × 10- 20 and 4.71 × 10- 20 cm2 in LKBBT system, and 3.85 × 10- 20, 7.20 × 10- 20 and 3.10 × 10- 20 cm2 in LKBBG system, respectively. Large Ω2 values indicate higher asymmetry and stronger covalent environment in them. The branching ratios for 1G4 → 3H5 transition of Pr3 + in the two glass systems arrive at 60.5% and 56.9%, respectively, and the predicted spontaneous-radiative transition rates are as high as 1188 and 1112 s- 1, which are beneficial in achieving efficient 1.3 μ m emission under the pumping of 1.03 μ m laser sources. © 2008 Elsevier B.V.
