Abstract

We have fabricated and characterized optically Nd 3 + -doped phosphate [ Li 2 O - CaO - BaO - Al 2 O 3 - La 2 O 3 - P 2 O 5 (LCBALP)] glasses for drawing single-mode glass fiber. The F 3 / 2 4 I 13 / 2 4 transition emission from the Nd 3 + is at the 1.327 μm wavelength with a full width at half-maximum of 43 nm , and the spontaneous transition probability and quantum efficiency are calculated to be 1836 s 1 and 52%, respectively. The maximum stimulated emission cross sections for F 3 / 2 4 I 11 / 2 4 and F 3 / 2 4 I 13 / 2 4 transitions are derived to be 1.82 × 10 20 cm 2 and 6.97 × 10 21 cm 2 , respectively, and the theoretical gain coefficient at the 1.327 μm wavelength is evaluated to be 0.182 dB / cm when the fractional factor of the excited neodymium ions equals 0.6, which indicates that Nd 3 + -doped LCBALP phosphate glasses are potential candidates in developing O-band optical fiber amplifiers.
