Title
(EN) Method and a system for generating a Raman second Stokes light to a source light
Abstract
(EN)

A method and system for generating a Raman second Stokes light to a source light comprising generating a Raman first Stokes light from the source light by a Raman interaction in a nonlinear optical medium disposed in an optical resonator, and resonating the Raman first Stokes light in the optical resonator; generating a seed light at the frequency of the Raman second Stokes light from the source light and the Raman first Stokes light by a four wave mixing process which is not phase matched in the nonlinear medium; amplifying the seed light by transferring power from the first Stokes light resonating in the optical resonator to the seed light using a Raman amplification process in the nonlinear medium; and extracting from the optical resonator a majority of the power of the seed light so amplified.
