Description/Abstract
A fully connectorised diode laser pumped first window amplifier has been constructed, for the first time, around a thulium doped fluoride fibre. For a 780/806nm combination of pump and signal wavelengths, small signal gains of 25-26dB and gain efficiencies of 2.4dB/mW have been achieved. In addition, output powers approaching +13dBm are possible for a launched pump power of 31mW, which corresponds to a conversion efficiency of around 65%.
