Popis: The optical properties of praseodymium-doped low-phonon-energy glasses have recently attracted considerable attention for their potential application as a 1.3 μm Pr +3 -doped optical fibre amplifier. Sulphide glasses based on Ga 2 S 3 and La 2 S 3 are amongst the lowest-phonon-energy glasses which are suitable for this application, with quantum efficiencies exceeding 50% currently measured on bulk samples in the laboratory. The purpose of this paper is to describe the thermal, optical and spectroscopic properties of Pr +3 -doped sulphide-based glasses, present the results of amplifier modelling using the measured cross-sections, and report the progress to date in achievement of a Pr +3 -doped sulphide-based fibre.
