|a The potential for optical amplification at 1.3 µm is demonstrated in a dysprosium-doped gallium-lanthanum-sulphide based glass. Lifetimes of 59µs are observed for the <sup>6</sup>H<sub>9/2</sub> - <sup>6</sup>H<sub>15/2</sub> transition for which the emission peaks at 1.32µm. A radiative lifetime of 203µs is calculated by a Judd-Ofelt analysis, indicating a total radiative quantum efficiency of 29%. A pump absorption cross-section 20 times greater than Pr<sup>3+</sup> suggests that shorter fibre devices may be possible.
