  We demonstrate a simple module for octave spanning continuous-wave
supercontinuum generation using standard telecom fiber. This module can accept
any high power Ytterbium-doped fiber laser as input. The input light is
transferred into the anomalous dispersion region of the telecom fiber through a
cascade of Raman shifts. A recently proposed Raman laser architecture with
distributed feedback efficiently performs these Raman conversions. A spectrum
spanning over 1000nm(>1 octave) from 880-1900nm is demonstrated. The average
power from the supercontinuum is ~34W with a high conversion efficiency of 44%.
Input wavelength agility is demonstrated with similar supercontinua over a wide
input wavelength range.
