摘要： The disclosure herein generally relates to a system (10) for converting an input light (12) into an output light beam (14) that has a spatial beam quality that is greater than that of the input light (12). The system (10) comprises an optical resonator having disposed therein a Raman crystal (20). The Raman crystal (20) is for receiving the input light (12) and the optical resonator is configured to resonate a Stokes light beam (22) generated from the input light (12) by at least one nonlinear interaction within the Raman crystal (20). The at least one nonlinear interaction comprises at least one Raman interaction. The Stokes light beam (22) has a spatial beam quality that is greater than that of the input light (12). The system (10) comprises a light extractor (18) arranged to generate the output light beam (14) by extracting at least some of the Stokes light beam (22) from the optical resonator.

摘要： 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.
