“…The shielding effect is attributed to ions and electrons produced by photodesorption induced by the coupling laser at the cell inner surfaces. In the presence of an additional radio-frequency field, the shielding effect persists and is reduced by an external high-frequency field (higher than dozens of MHz) [32]. Therefore, the spectral lines broadening from the Stark shifts with the ambient static and low-frequency alternating electric field is negligible.…”

We demonstrate the single-photon excitation spectra of cesium Rydberg atoms by means of a Doppler-free purely all-optical detection with a room-temperature vapor cell and a 319 nm ultraviolet (UV) laser. We excite atoms directly from 6S 1/2 ground state to 71P 3/2 Rydberg state with a narrow-linewidth 319 nm UV laser. The detection of Rydberg states is performed by monitoring the absorption of an 852 nm probe beam in a V-type three-level system. With a strong coupling light, we observe the Autler-Townes doublet and investigate experimentally the dependence of the separation and linewidth on the coupling intensity, which is consistent with the prediction based on the dressed state theory. We further investigate the Rydberg spectra with an external magnetic field. The existence of non-degenerate Zeeman sub-levels results in the broadening and shift of the spectra. It has potential application in sensing magnetic field.

“…For a three-level scheme, the observed spectrum in a room-temperature vapor cell is usually velocity-dependent [20,21]. Taking into account Doppler effect, the probe laser's frequency for atoms with different velocity groups is:…”

Abstract:We demonstrate a single-photon Rydberg excitation spectroscopy of cesium (Cs) atoms in a room-temperature vapor cell. Cs atoms are excited directly from 6S 1/2 ground state to nP 3/2 (n = 70 -100) Rydberg states with a 318.6 nm ultraviolet (UV) laser, and Rydberg excitation spectra are obtained by transmission enhancement of a probe beam resonant to Cs 6S 1/2 , F = 4 -6P 3/2 , F' = 5 transition as partial population on F = 4 ground state are transferred to Rydberg state. Analysis reveals that the observed spectra are velocity-selective spectroscopy of Rydberg state, from which the amplitude and linewidth influenced by lasers' Rabi frequency have been investigated. Fitting to energies of Cs nP 3/2 (n = 70 -100) states, the determined quantum defect is 3.56671(42). The demodulated spectra can also be employed as frequency references to stabilize the UV laser frequency to specific Cs Rydberg transition.

“…The main peak at 0 detuning in the field-free spectrum corresponds to the |6S 1/2 F = 4 → |6P 3/2 F ′ = 5 → |60D 5/2 cascade EIT. The small peak at -168 MHz (small arrow) originates in the intermediate-state hyperfine level |6P 3/2 , F ′ = 4[15]. The peak at -318 MHz is the 60D 3/2 EIT line.…”

We investigate atom-based electric-field calibration and polarization measurement of a 100-MHz linearly polarized radio-frequency (RF) field using cesium Rydberg-atom electromagnetically induced transparency (EIT) in a room-temperature vapor cell. The calibration method is based on matching experimental data with the results of a theoretical Floquet model. The utilized 60DJ fine structure Floquet levels exhibit J-and mj-dependent AC Stark shifts and splittings, and develop even-order RF-modulation sidebands. The Floquet map of cesium 60DJ fine structure states exhibits a series of exact crossings between states of different mj, which are not RF-coupled. These exact level crossings are employed to perform a rapid and precise (±0.5%) calibration of the RF electric field. We also map out three series of narrow avoided crossings between fine structure Floquet levels of equal mj and different J, which are weakly coupled by the RF field via a Raman process. The coupling leads to narrow avoided crossings that can also be applied as spectroscopic markers for RF field calibration. We further find that the line-strength ratio of intersecting Floquet levels with different mj provides a fast and robust measurement of the RF field's polarization.
