Parametric resonance magnetometer response: comparison between the theoretical prediction (with no free parameters) and the experimental data. (a) Superposition of experimental measurements (color disks) for different optical powers (given in the inset, with 10% systematic uncertainty coming from optical power calibration) and theoretical predictions (solid lines). (b) Slopes of the dispersive response near the null magnetic field, as a function of the optical power: experimental data (blue crosses) and theoretical predictions (blue solid line)
