Data associated with the publication "Electromagnetically induced transparency and population repump readout of
Rydberg states of Cs atoms in a J-scheme".
Rydberg atom electrometry offers traceable electric field measurements over many decades of radio frequencies
in a single device. Miniaturization of these sensors is primarily limited by requirements of the lasers used. Here
we demonstrate a three-photon sensing scheme using a J-shaped energy level coupling that can be achieved
using external cavity diode lasers, without the need for a doubling crystal or tapered amplifier. In the low
laser power regime, we demonstrate a full-width at half-maximum linewidth of 1.3 MHz. We demonstrate that
for RF field electrometry using conventional heterodyne techniques, we can detect 4.7 GHz at a sensitivity of
27 μV m−1 Hz−1/2, comparable to that of two-photon detection schemes which require the use of a tapered
amplifier. We also investigate a modified scheme where the probe laser is locked to a different hyperfine state,
thus measuring the two-photon EIT in the other two lasers via the change in population of this separate state
due to repumping. In this scheme we find the sensitivity for a 4.7 GHz field to be 39 μV m−1 Hz−1/2, and
demonstrate that the amplitude scaling with probe power offers a different saturation profile than the linked
J-scheme counterpart.
