title: High-power Ho-doped all-fiber superfluorescent source pumped by a 1150  nm Raman fiber laser.
abstract: A broadband superfluorescent source based on 2 m long Ho-doped fiber and a 1150 nm high-power Raman fiber laser is reported. The optical spectrum of the superfluorescent source spans the range from 1930 to 2110 nm. The maximum output power is 1.5 W, and the spectral full width at half-maximum is about 30 nm. Two peaks are generated in an optical spectrum when output power of the Ho-doped superfluorescent source is beyond ∼200  mW.
