Supercontinuum around 1550 nm using a dual- wavelength coherent ultrashort pulse source is demonstrated.Dual-wavelength pulse pumping can strengthen the processes of four-wave-mixing and crossphase-modulation, thus, it generates a much broader supercontinuum than regular single- wavelength pumping at the same pump power. Based on pulse carver and Mamyshev regenerator 25 GHz dual-wavelength coherent ultrashort pulse source,130 nm supercontinuum is experimentally obtained with a pump power of 24.1 dBm.Coherence between the spectral lines is also verified.
