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 780/806 nm combination of pump and signal wavelengths, small signal gains of 25–26 dB and gain efficiencies of 2.4 dB/mW have been achieved. In addition, output powers approaching +13 dBm are possible for a launched pump power of 31 mW, which corresponds to a conversion efficiency of around 65%.Keywords
