We report the design and demonstration of novel 2050 nm Watt-level Ho-doped fibre amplifiers that are pumped with broad spectrum Watt-level Tm-doped ASE sources centred at 1860 nm instead of conventional narrow linewidth semiconductor or fibre laser sources. Our approach is simpler and more cost effective than the standard laser based pumping means, and leads to similar amplifier performance.
