High-power operation of a single-mode, linearly polarized, broadband superfluorescent fiber source has been achieved by using a two-stage cladding-pumped fiber configuration comprising a low power, single-ended, ytterbium-doped superfluorescent fiber seed source and a high-power cladding-pumped, polarization-maintaining, large-mode-area, ytterbium-doped amplifier pumped by a high-power diode source at 976 nm . The source yielded a maximum linearly polarized output of 106 W with a slope efficiency of up to 67% with respect to the launched pump power and with a measured polarization extinction ratio of 13.5 dB . The wavelength spectrum of the superfluorescent source spanned the range continuously from 1035 to 1100 nm , and the bandwidth (FWHM) of the emission spectrum was 21 nm . The minimum seed power required for an output power over 100 W was only 10 mW , corresponding to an effective power gain in the amplifier stage of 40 dB . Single-spatial-mode operation with a beam propagation factor ( M 2 ) < 1.1 was achieved by bending the amplifier fiber to a bend radius of 8 cm , without a significant reduction in output power.
