Abstract
In a Raman system, a primary laser source emits laser light at an initial wavelength, and a seed source emits a multi-wavelength seed laser light. The seed wavelengths correspond to a respective Stokes orders of the primary laser light. The primary laser light and the seed laser light are combined and fed into a Raman gain medium. Stimulated Raman scattering (SRS) causes the primary laser light to be converted into laser light at a selected target wavelength. The seeding of the primary light mediates the conversion process, so as to reduce spontaneous Raman scattering.
