摘要: We utilize an electromagnetically induced transparency (EIT) of a three-level cascade system involving Rydberg state in a room-temperature cell, formed with a cesium 6S1/2-6P3/2-66S1/2 scheme, to investigate the Autler-Townes (AT) splitting resulting from a 15.21-GHz radio-frequency (RF) field that couples the|66S1/2>→|65P1/2> Rydberg transition. The radio-frequency electric field induced AT splitting, γAT, is defined as the peak-to-peak distance of an EIT-AT spectrum. The dependence of AT splitting γAT on the probe and coupling Rabi frequency, Ωp and Ωc, is investigated. It is found that the EIT-AT splitting strongly depends on the EIT linewidth that is related to the probe and coupling Rabi frequency in a weak RF-field regime. Using a narrow linewidth EIT spectrum would decrease the uncertainty of the RF field measurements. This work provides new experimental evidence for the theoretical framework in[J. Appl. Phys. 121, 233106 (2017)].
