  • Abstract
    The potential for optical amplification at 1.3 μm is demonstrated in a dysprosium-doped gallium-lanthanum-sulphide based glass. Lifetimes of 59 μs are observed for the 6H9/2-6H 15/2 transition for which the emission peaks at 1.32 μm. A radiative lifetime of 203 μs is calculated by a Judd-Ofelt analysis, indicating a total radiative quantum efficiency of 29%. A pump absorption cross-section 20 times greater than Pr3+ suggests that shorter fibre devices may be possible
