Ultrafast Sources at On-Demand Wavelengths via Seeded Intermodal Raman Scattering

We numerically show that controlling the power of a low-power 500 ps-pulse seed can, via intermodal Raman scattering, tune the wavelength of a ~MW peak power level 100-fs soliton, yielding a versatile color-tunable all-fiber energetic ultrafast pulse source.
