NOVEL HEAVY METAL MODIFIED SILICA GLASS FIBERS DOPED WITH THULIUM, HOLMIUM, AND THULIUM-SENSITIZED-HOLMIUM HIGH QUANTUM EFFICIENCIES

摘要

A modified silica glass composition for providing a reduction in the multiphonon quenching for a rare-earth dopant comprising: SiO2 in a host material; a rare-earth dopant; a first SiO2 modifier; and a second SiO2 modifier; such that said first modifier and said second modifier reduce multiphonon quenching of the rare-earth dopant contained therein.
