Simultaneous Use of Cs and Rb Rydberg Atoms for Dipole Moment Assessment and RF Electric Field Measurements via Electromagnetically Induced Transparency
Christopher L. Holloway, Matthew T. Simons, Joshua A. Gordon
We demonstrate simultaneous electromagnetically-induced transparency (EIT) with cesium and rubidium Rydberg atoms in the same vapor cell with coincident (overlapping) optical fields. Each atomic system can detect RF electric (E) field strengths through modification of the EIT signal, which lead to a direct SI traceable RF E-field measurement. We show that these two systems can detect the same the RF E-field strength simultaneously. In effect, this allows us to perform two independent measurements of the same quantity in the same laboratory, providing two different immediate and independent measurements. We examine the impact of coincident, simultaneous EIT on RF field metrology and the EIT signal. We use this approach to measure E- fields at 9.2~GHz, 11.6~GHz, and 13.4~GHz, which correspond to three different atomic states (different principal atomic numbers and different angular momentums) for the two different atom species.
