Rabi decay under image pumping condition at 40 K. The decay of the Rabi oscillations (green) for a Mn\(^{2+}\) spin is limited by the relaxation time \(T_1\) (orange) when an image pulse is used to sustain the dynamics. The inset shows the long-lived oscillations, all the way up to the 15 \(\upmu\)s limit as imposed by the power amplifier of the setup.
