Description/Abstract
A fully connectorized diode laser pumped first window amplifier has been constructed, for the first time, around a thulium doped fluoride fiber. For a 780/806 nm combination of pump and signal wavelengths intrinsic 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 from the doped fiber were possible for launched pump powers of 31 mW, which corresponds to a pump to signal conversion efficiency of around 64%. Minimum noise figures of 4 - 5 dB have been achieved with characteristics which mirror the output power performance. The 3 dB gain bandwidth for this transition has been measured at 9 - 10 nm for small signals, increasing to better than 15 nm under signal saturation conditions
