Praseodymium-doped cadmium mixed halide glasses for 1.3 μm amplification

In the search for suitable glass hosts for 1300 nm amplification, the field has been narrowed to Pr-doped fluorozirconate, fluoroindate, cadmium mixed halide and sulphide glasses. This paper presents data identifying the cadmium mixed halide system as a leading candidate, based on the lifetime and q...

Description
Summary:In the search for suitable glass hosts for 1300 nm amplification, the field has been narrowed to Pr-doped fluorozirconate, fluoroindate, cadmium mixed halide and sulphide glasses. This paper presents data identifying the cadmium mixed halide system as a leading candidate, based on the lifetime and quantum efficiency of the1G4 →3H5 fluorescence of Pr3+ in this system. Compositional studies to develop cladding and core glasses suitable for high numerical aperture fiber, as well as relevant physical and optical properties, are also discussed.
