Abstract: We propose a cavity-based combined Raman and second harmonic generation scheme for generating hundreds of milliwatts of continuous-wave yellow radiation with a frequency linewidth suitable for spectroscopic applications. We suggest using H2 gas as the Raman medium in an external Raman ring resonator with an intracavity frequency doubling crystal. Using gas rather than a crystal allows for single-mode, narrow-linewidth operation suitable for many spectroscopic applications. In a specific numerical example, we predict the generation of more than 200 mW of narrow-linewidth 583 nm light from an input of 1 W of 785 nm light, which could be obtained from a low cost tapered amplifier diode system. Finally, we suggest methods for improving the laser performance.
