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.

First claim

What is claimed is:

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…
