| 摘 要： | A new approach is introduced to enhance supercontinuum （SC） spectrum in a dispersion-flattened/decreasing fibre with a convex dispersion profile. A flat SC spectrum nearly extending from 1200hm to 2100hm can be generated based on this scheme. It is found that group-velocity dispersions （GVD） and self-phase modulation （SPM） effects are the primary factors for pump Raman scattering （SRS） effect plays an essential self-steepening effect can be ignored. pulse compression and SC spectrum generation, stimulated role on the final SC-spectrum bandwidth and flatness, but
