Abstract

High power operation of an ytterbium-doped multi-core ribbon fiber laser and a cladding pumped ytterbium-doped helical core fiber laser is reported. 320W laser output at 1045nm was demonstrated with a 10-core ytterbium doped ribbon fibre. Efficient single-mode operation of a cladding-pumped ytterbium-doped helical-core fiber laser with a 30 µm diameter core and a numerical aperture of 0.087 have also been demonstrated. The laser yielded 60.4 W of output at 1043 nm in a beam with M 1.4 for 92.6 W launched pump power from a diode stack at 976 nm. Further more, the recently progress of a cladding-pumped ytterbium-doped helical-core superfluorescent fiber source is also reported. The highly efficient operation of the helical core fiber ASE source yielded 107W of amplified spontaneous emission output spanning the wavelength range from 1030-1160nm with a bandwidth (FWHM) of 37nm.
