Abstract
Glasses based on rare earth oxides and aluminum oxide with 0-20 mol% SiO2 provide a combination of optical properties, mechanical and chemical stability, and process characteristics not available in other oxide materials. Properties of the glasses include: refractive index 1.7-1.8, low dispersion (Abbe number ∼40), high solubility of optically active dopants, homogeneous chemical composition, long fluorescence lifetimes at dopant concentrations up to 5 mol%, broad fluorescence bandwidth, and infra-red transmission to ≈5000nm. the glasses are hard, strong and resist chemical attack and they can be cast in sections 5-10mm thick. This paper briefly describes glass processing and presents bulk glass properties including results of experiments to study infra-red fluorescence at wavelengths ∼1550, ∼2900 and ∼1030nm from Er- and Yb-doped glasses that were optically pumped at 980 nm. © 2004 Elsevier B.V.
