Resonant stimulated electronic Raman scattering in potassium vapor. Dispersion near principal doublet and influence of four-photon processes
V. I. Anikin, S V Kryuchkov, V. E. Ogluzdin
An experimental investigation was made of the resonant stimulated electronic Raman scattering near the principal doublet of potassium. A study was made of the dispersion, interaction of two- and three-photon scattering, and influence of four-photon processes. Possible mechanisms of the population of the 4 2 P 1/2 and 4 2 P 3/2 potassium levels were considered. The possibility of phase-matched four-photon parametric interactions in the investigated part of the spectrum was confirmed theoretically.
