Emission at 1.3 microns from dysprosium-doped Ga:La:S glass

Record type: Article

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 6H(9/2) - 6H(15/2) 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 Pr3+ suggests that shorter fibre devices may be possible.
