20090033871 | Opthalmic optical coherence tomography (OCT) test station using a 1um fiber ASE source - A phosphate glass 1-μm fiber ASE source provides high power and broadband emission that covers wavelengths on the short side of Yb-doped silica. A single-mode fiber formed from phosphate glass is doped with highly elevated concentrations of Yb dopants 0.5-30 wt. % and typically 2-10 wt. %, far higher than either silica or germano-silicate.
