Abstract We report a highly efficient ytterbium-doped double-clad fibre laser, one-end pumped by a 975-nm diode stack source and generating up to 115.6 W of cw output power at 1.1 μm. The maximum optical-to-optical conversion efficiency with respect to the launched pump power is 79% at 65-W output power, and the overall slope efficiency is about 69%.
