Fig. 3: Observation of the Mollow triplet.
From: Resonance fluorescence and indistinguishable photons from a coherently driven B centre in hBN

a Dots: count rate as a function of the detuning of the scanning FP filter at eight different powers. Plain line: fit to the data. b Circles: Rabi frequency extracted from the Mollow triplet splitting. Plain line: fit to the data. Stars: Rabi frequency extracted from the ZPL g (2) oscillations. Error bars: 1 standard deviation.
