Abstract

The synthesis and optical properties of Pr-doped GeGaS glasses are reported. The radiative properties associated with the important 1G43H5 transition of Pr3+ at 1.3 μm have been determined by absorption and fluorescence measurements coupled with Judd-Ofelt analysis. As compared with ZBLAN glass, Pr-doped GeGaS glasses have a longer fluorescence lifetime and a larger stimulated emission cross-section, which are favorable for an efficient fiber amplifier. The concentration quenching of Pr3+ in these glasses has also been studied by fluorescence lifetime measurements.
