Supercontinuum(SC) light sources with high powers and broad spectra are widely employed in the fields of spectroscopy and biomedicine. Several schemes for high power supercontinuum generation based on the passive and active fibers are introduced, various schemes are compared in the aspects of fiber materials, bandwidth, and output power. In this paper, it is pointed out that the reasonable selection of fiber type or structure is conducive to the improvement of SC bandwidth and output power.
