Abstract:
1. A light generation and amplification system, comprising: a Raman gain medium; a primary laser source for emitting a primary laser light at an initial wavelength; a seed source for emitting a multi-wavelength seed laser light, comprising a plurality of seed wavelengths corresponding to a series of Stokes orders generated by the primary laser light in the Raman gain medium, wherein the series of Stokes order includes one or more intermediate Stokes orders and a final Stokes order at a selected target wavelength; and a seed light combiner for combining the primary laser light and the seed laser light into a combined laser light and providing the combined laser light as an input into the Raman gain medium, wherein the primary laser light and seed laser light components of the combined laser light have intensities that are sufficient to create, within the principal Raman gain medium, cascaded stimulated Raman scattering at each of the intermediate Stokes orders and at the final Stokes order, whereby the primary laser light at the initial wavelength is converted to a system output laser light at the target wavelength, wherein the seed source comprises a plurality of seed lasers providing different respective sets of seed wavelengths, so as to enable a multi-wavelength system output, and wherein the seed lasers are configured to provide individually selectable power outputs, so as to provide selectable power levels for individual wavelengths of the system output.
