Characterization of a dissipative Rabi system. Symbols are experimental data. Solid lines are theoretical fits. a In the presence of the RF field but without the dissipative optical field, atom numbers $n_{\sigma }^{\prime }\left(t\right)$ show Rabi oscillations with a Rabi frequency of 2J = (2π) × 2.15 kHz. b In the presence of an optical field resonant with |↓〉 but without the RF field, $n_{\downarrow }^{\prime }\left(t\right)$ shows an exponential decay: Γ = 0.30J (red squares), Γ = 0.98J (black triangles), Γ = 2.35J (green diamonds). $n_{\uparrow }^{\prime }\left(t\right)$ remains almost constant during the experimental time. Blue circles show $n_{\uparrow }^{\prime }\left(t\right)$ when Γ = 0.30J
