摘要：

Absorption and emission spectra, along with lifetime measurements, of Dy3+ in Ge-Ga-S glasses are reported. Fluorescence is observed at 1.3, 1.8, and 2.9 mum. A Judd-Ofelt analysis is performed to determine branching ratios and quantum efficiencies. The hypersensitive transition F-6(11/2) --> H-6(15/2) at 1.3 mum has a quantum efficiency of 17%. Its suitability for an optical amplifier at 1.3 mum depends on the excited-state absorption from the H-6(11/2) and H-6(13/2) states, which has not yet been measured.
