The optical properties of praseodymium-doped low-phonon energy glasses have recently attracted considerable attention for their potential application as a 1.3μm Pr3+-doped optical fibre amplifier. Sulphide glasses based on Ga2S3 and La2S3 are amongst the lowest phonon energy glass which are suitable for this application, with quantum efficiencies exceeding 50% currently measured on bulk samples in our laboratory. The purpose of this paper is to describe the thermal, optical and spectroscopic properties of Pr3+-doped sulphide based glasses and report on progress to date in achievement of a Pr3+-doped sulphide based fibre.
