Four-wave mixing in a non-degenerate four-level diamond configuration in the hyperfine Paschen-Back regime

We present an experimental study of seeded four-wave mixing (4WM) using a diamond excitation scheme (with states from the 5S\(_{1/2}\), 5P\(_{1/2}\), 5P\(_{3/2}\) and 5D\(_{3/2}\) terms) in a thermal vapour of \(^{87}\)Rb atoms. We investigate the 4WM spectra under the application of a strong magnet...

Description
Summary:We present an experimental study of seeded four-wave mixing (4WM) using a diamond excitation scheme (with states from the 5S\(_{1/2}\), 5P\(_{1/2}\), 5P\(_{3/2}\) and 5D\(_{3/2}\) terms) in a thermal vapour of \(^{87}\)Rb atoms. We investigate the 4WM spectra under the application of a strong magnetic field (0.6 T). The Zeeman interaction is strong enough to realise the hyperfine Paschen-Back regime, which has the effect of separating the optical transitions by more than the Doppler width, thereby significantly simplifying the spectral features. We show that this facilitates a quantitative comparison, even in the regime of strong dressing, between experimental data and a simple theoretical model based only on four-level optical Bloch equations.
