Abstract :
The authors reported a 106 W single-mode, single-ended fibre superfluorescent source with a linearly-polarized output beam based on a simple two-stage configuration comprising a cladding-pumped Yb-doped fibre superfluorescent seed stage and a polarization-maintaining (PM) cladding-pumped Yb-doped fibre amplifier stage. The experimental set-up is shown. The seed-stage comprised a 7-m-long Yb-doped double-clad fibre and a 15 W diode pump source at 915nm. The fibre had a 20-alpham-diameter Yb-doped alumino-silicate core with a numerical aperture (NA) of 0.06, and a pure silica inner-cladding of diameter, 400-alpham.
