Abstract:We derive a numerical model of visible Raman lasers that employ simultaneous intracavity Raman shifting and intracavity second-harmonic or sum-frequency generation. We show excellent agreement with previous experimental results, and explain the mechanism by which sum-frequency generation can inhibit the generation of the Stokes field. We predict that increased output powers should be achieved using unusually short crystals of only few millimeters length.
