Ytterbium-doped large-core fibre laser with 610 W of near diffraction-limited output power
We report a cladding-pumped ytterbium-doped fibre laser, generating up to 610 W of continuous-wave (cw) output power at 1.1 micron with slope efficiency of 80% and near diffraction-limited beam quality (M2 = 1.3). No undesirable roll-over was observed in output power with increasing pump power.
