Abstract

Efficient emission at 1.38 μ m wavelength from holmium ( Ho 3 + ) -doped low-phonon-energy gallate bismuth lead (GBL) oxide glasses, owing to the Ho 3 + : ( S 2 5 , F 4 5 ) I 5 5 transition, was observed, and the stimulated emission cross section was calculated to be 2.4 × 10 21 cm 2 . Population inversions between the ( S 2 5 , F 4 5 ) and I 5 5 levels have been achieved, and a broad gain bandwidth from 1350 to 1450 nm was obtained. The large product of emission cross section and measured lifetime also support this characteristic. The results indicate that a Ho 3 + -doped GBL glass system is a promising candidate for the development of E-band ( 1360 1460 nm ) fiber-optic amplifiers.
