High-power broadband ytterbium-doped helical-core fiber superfluorescent source
High-power broadband ytterbium-doped helical-core fiber superfluorescent source
Highly efficient operation of a double-clad ytterbium-doped helical-core fiber in a superfluorescent (nonlasing) configuration has been demonstrated. The fiber was cladding-pumped by a diode-stack at 976 nm and yielded 107 W of amplified spontaneous emission from the two ends of the fiber for 168 W of absorbed pump power in an output beam with a beam propagation factor (M) of 2.8. At pump powers over 40 W, the slope efficiency with respect to the absorbed pump power was 76%. The emission spectrum spanned the wavelength range from 1030 to 1160 nm and the bandwidth (full-width at half-maximum) was 37 nm.

Abstract
Highly efficient operation of a double-clad ytterbium-doped helical-core fiber in a superfluorescent (nonlasing) configuration has been demonstrated. The fiber was cladding-pumped by a diode-stack at 976 nm and yielded 107 W of amplified spontaneous emission from the two ends of the fiber for 168 W of absorbed pump power in an output beam with a beam propagation factor (M) of 2.8. At pump powers over 40 W, the slope efficiency with respect to the absorbed pump power was 76%. The emission spectrum spanned the wavelength range from 1030 to 1160 nm and the bandwidth (full-width at half-maximum) was 37 nm.
