Abstract
The characteristics of backward Yb-doped double-cladding fiber superfluorescent were reported in this paper. The maximum output power of double-pass backward super-fluorescent is 2.1W with slope efficiency of 51.5% and the single-pass backward super-fluorescent is 1.1 W with slope efficiency of 29.5% with respect to absorbed pump power when the fiber length is only 2.8m. Finally, the self-oscillation of different length fiber was also discussed..
