Abstract

We present experimental results which indicate that a Dy3+-doped Ga:La:S glass fibre amplifier may be operated efficiently at 1.3μm with an optimum device length significantly shorter than a comparable Pr3+-doped one. Moreover, the efficiency exceeds that obtained from the Pr3+-doped ZBLAN devices currently available.
