Performance and limits of the method. a XY8 sequence employed to record the data of b, c. The signal was phase-cycled in order to maximize sensitivity. b Rabi oscillations much slower than \(T_2^{\boldsymbol{*}}\) = 1.8 μs, where the number of π pulses was increased up to 120 while keeping the pulse spacing τ and the signal power P constant. c Signal decay for increasing pulse spacing. For a spacing \(\tau >T_2^{\boldsymbol{*}}\), the pulsed Mollow protocol loses sensitivity. Data traces in b, c have been shifted vertically by an offset of 1.0 for better comparison
