RF induced ODMR signals recorded as a function of B z and time in two RF-intensity regimes: \({{\rm{\Omega }}}_{R}\,\lessgtr \,{\gamma }_{gg\text{'}}\). (a) Weak-field regime, B RF ≈ 200 μG at \({\omega }_{RF}\) = \(2\pi \) 10 kHz. The dashed line indicates time at which RF field is turned on. (b) Strong-field regime, B RF ≈ 7 mG at \({\omega }_{RF}\) = \(2\pi \) 20 kHz, revealing RF induced Rabi oscillations seen as horizontal bell-shaped fringes. Minimum oscillation frequency is around +/−43 mG. The central feature in both figures is an artefact of the sample preparation process. (c) A signal of RF induced Rabi oscillations observed by the relaxation in the dark method. The individual signals decay with τ = 1.56 ms, while the envelope with τ = 5 ms; a rate that is comparable with the calculated rate of atoms leaving the interaction area.
