摘要：

We report the highest power operation of a resonantly cladding-pumped, holmium- doped silica fibre laser. The cladding pumped all-glass fibre utilises a fluorine doped glass layer to provide low loss cladding guidance of the 1.95 mu m pump radiation. The operation of both single mode and large-mode area fibre lasers was demonstrated, with up to 140 W of output power achieved. A slope efficiency of 59% versus launched pump power was demonstrated. The free running emission was measured to be 2.12-2.15 mu m demonstrating the potential of this architecture to address the long wavelength operation of silica based fibre lasers with high efficiency.
