Abstract
The output spectrum of Yb-doped double-clad fiber superfluorescent source (SFS) is tailored by placing a broadband dichroic mirror in the pump end of conventional single-pass forward configuration, which constitutes double-pass forward configuration. The 3Â dB bandwidth is increased from 11 to 42Â nm. A maximum output SFS power of 2.12Â W and a slope efficiency of 43.2% are obtained. The double-clad fiber is 25Â m and the pump power is adequate to saturate the fiber as far as the feedback-induced lasing appears.
