Abstract
We demonstrate the first gain-switched, singly doped, singlemode holmium-doped silicate glass fibre laser that operates at 2.106□m. Using a gain-switched 1.909-m thulium-doped fibre laser as the pump source, output pulses of energy 3.2 and pulse duration of 150 ns were generated at 80 kHz and slope efficiency of 44%. Pulse stacking within the holmium-doped fibre laser resulted in significantly shorter 70 ns pulses.
