Abstract

Glass and glass fibers formed from rare earth (RE) oxide-aluminum oxide compositions (REAlTM glasses) have properties similar to sapphire. They exhibit infrared transmission to wavelengths ~ 5000 nm; are hard and strong, thermally stable to ~ 1000°C, highly resistant to attack by aqueous solutions; and can be made into homogeneous products that contain large concentrations of optically active dopants. This paper describes the synthesis, optical properties, fluorescence lifetime measurements of Er³⁺- and Ho³⁺-doped glasses, and in-progress resaerch on materials that emit in the 2000-3000 nm wavelength range of interest for medical device applications. Effects of host glass compsition and dopant concentrations up to 32 mole% are presented.
