We present the results of stroboscopic microwave spectroscopy of a radio-frequency-dressed optically pumped magnetometer. The interaction between radio-frequency-dressed atoms and a synchronously pulsed microwave field followed by Voigt-effect-based optical probing allows us to perform a proper ground-state interrogation for dressed state and assess the efficiency of the state preparation process. This work shows that through the stroboscopic technique the microwave spectrum is simplified when compared to the continuous counterpart. This is a necessary step towards investigating vector magnetometers in unshielded environments, where the influence of the nonlinear Zeeman effect, a source of heading errors, would otherwise be spectrally unresolved in dressed states. To theoretically describe the system, we solve the dynamical equation of the density matrix employing Floquet expansion. Our theoretical results are in good agreement with experimental measurements over a wide range of parameters and pumping conditions. (AU) | |
