Abstract

Raman-heterodyne-detected complex nonlinear susceptibility has been measured and analyzed in detail with a radio-frequency field strength varying from weak to strong. The experiments were carried out on the nitrogen–vacancy color center in diamond involving both nuclear magnetic resonance and electron paramagnetic resonance transitions. The dispersive and the absorptive components of the nonlinear susceptibility are shown to have different saturation behaviors, and an anomalous-amplitude line shape arises where the dispersion component dominates in the response spectrum at high RF powers. The experimental results are found to be in good agreement with theoretical profiles, where no adjustable parameter is included in the calculation.
