摘要：

A highly efficient amplifier has been demonstrated using the 1470nm transition in a thulium doped fluoride fibre by upconversion pumping at 1064nm. A small signal gain bandwidth of 35 nm was shown with a gain peak of around 19dB occurring at 1462nm. A maximum gain efficiency of 0.24dB/mW, and output power of 17dBm have been achieved, the latter for a launched pump power of 155mW, indicating a power conversion efficiency of 34%.
