a The generated signal’s response to a variable magnetic field strength \({\overrightarrow{B}}_{z}\) along the z-axis. Wte operate at 209 mG for maximum generation. We fit a symmetric Fano profile [Eq. (6)] to these data, with fit parameters \({\eta }_{0}^{{\prime} }=0.95(2)\), γB = 200(4)mG and B0 = − 5(3)mG. This behavior might indicate the interaction and interference of multiple Zeeman level resonances within the decoherence width of our atoms. Error bars represent the standard deviation. b A close up of the unmodulated generated line revealing a FWHM of 26(2) Hz.
