Abstract
A system includes a laser configured to generate a pump beam at a pump wavelength. The system also includes a multi-media Raman resonator configured to receive the pump beam and generate an output beam. The multi-media Raman resonator includes multiple mirrors and multiple Raman media optically located between the minors. Output power in the output beam is spectrally concentrated around a single dominant wavelength that is longer than a pump wavelength. The longer wavelength of the output beam is associated with a combination of at least one Stokes shift associated with each of the individual Raman media. A filter could be configured to absorb light at a wavelength that is absorbed by one of the Raman media or to redirect light at the wavelength absorbed by one of the Raman media away from that Raman medium.
