“…We use the solutions listed in (13)-(15), (23), and (24) to construct a mapping that represents passing through the SFG and SRS interactions. 1 We multiply 1 Jacobi elliptic functions were computed using programs in [8]. the Stokes flux density exiting the SRS interaction by the cavity reflectivity and use the result for the input to the next round trip around the cavity.…”

“…We have developed a numerical-integration code based on fast Fourier transforms and fourth-order Runge-Kutta integration to address such concerns. We use this code, described previously [1], [10], to model the SFG SRS device described above. The calcula- tions require about 200 passes of the Stokes field through the resonator to reach steady state.…”

“…R ECENTLY, we examined a Raman oscillator containing an intracavity second-harmonic generator that frequency doubles the resonant Stokes field [1]. We found that there is an optimum ratio between the nonlinear coupling of the stimulated Raman scattering (SRS) and the nonlinear coupling of the intracavity second-harmonic generation (SHG) for maximizing the second harmonic of the Stokes frequency.…”

We use a plane-wave analysis to examine a Raman oscillator containing an intracavity sum-frequency interaction that frequency sums the circulating first-order Stokes radiation with the pump radiation. We find that there is an optimum ratio between the nonlinear coupling in the Raman medium and the nonlinear coupling in the sum-frequency generator. We also find that higher order Stokes radiation should be suppressed with the optimum choice of nonlinear coupling in the sumfrequency interaction. Numerical integration of the equations containing transverse effects predicts a time-averaged powerconversion efficiency of 61.4% for conversion of 532-to 273.5-nm radiation using a CW mode-locked frequency-doubled Nd:YAG laser with Ba(NO2)3 for the Raman material and CsLiB6O10 (CLBO) for the sum-frequency material.

“…The balance between the efficiency of the SRS and SHG processes in these types of lasers is emphasized in [7]; an imbalance of SRS and SHG efficiencies can either result in inefficient conversion of the circulating Stokes field or can prevent the Stokes field from building to an appreciable power in the cavity. Figure 4 illustrates this balance, showing a clear decrease in the overall NIR to yellow conversion past an optimum SHG crystal length.…”

“…Other methods for producing light in this region use SHG together with stimulated Raman scattering (SRS), a χ 3 process, inside an optical cavity [7]. These techniques have been quite successful in generating yellow light with CW powers near 3 W from all-solid-state configurations [8,9], and progress is being made in using the superior nonlinear and thermal properties of diamond [10] to produce CW Raman lasers as well [11].…”

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 H 2 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.
