“…[12]). Bason et al [13] used nonresonant dressing fields to increase the sensitivity of Rydberg state energies to dc electric fields, and Sevinçli and Pohl [14] have explored the influence of multiple dressing fields on Rydberg-Rydberg interactions. Recently, Jones et al [15] experimentally demonstrated a significant reduction in the electric field dependence of low-ℓ Rydberg-Rydberg transition frequencies through the application of a non-resonant dressing field.…”

Non-resonant dressing fields can make the transition frequency between two circular Rydberg states insensitive to second order variations in the dc electric field. Perturbation theory can be used to establish the required dressing field amplitude and frequency. The same perturbative approach may be used to understand removal of the first order dependence of the transition frequency on electric field about a bias dc electric field [Hyafil et al. Phys. Rev. Lett. 93, 103001 (2004)]. The directional alignment of the dressing and dc fields is critical in determining the electric field sensitivity of the dressed transition frequencies. This sensitivity is significantly larger for circular Rydberg states compared to low-angular momentum Rydberg states of Rb.

“…Spectroscopy of excited state transitions is of growing interest for a variety of applications including the search for stable frequency references [1,2], state lifetime measurement [3], optical filtering [4], frequency up-conversion [5], multiphoton laser cooling [6], as well as Rydberg gases [7,8] and their application to electro-optics [9][10][11] and nonlinear optics [12]. Twophoton excited state spectroscopy can be achieved without significant transfer of population out of the ground state using electromagnetically induced transparency (EIT) [13] in the ladder configuration [14].…”

We investigate, theoretically and experimentally, absorption on an excited-state atomic transition in a thermal vapor where the lower state is coherently pumped. We find that the transition linewidth can be subnatural, that is, less than the combined linewidth of the lower and upper state. For the specific case of the 6P 3/2 → 7S 1/2 transition in room temperature cesium vapor, we measure a minimum linewidth of 6.6 MHz compared with the natural width of 8.5 MHz. Using perturbation techniques, an expression for the complex susceptibility is obtained which provides excellent agreement with the measured spectra.

“…For example, Rydberg EIT has been used to modify the frequency of light [11], study interactions in cold Rydberg gases [12,13,14] and probe electric fields inside vapour cells [15,16] and close to surfaces [17]. A feature of Rydberg states is the large dipole moment to nearby states which scales with the square of the principal quantum number, n 2 .…”

Abstract. We study electromagnetically induced transparency (EIT) in the 5s→5p→46s ladder system of a cold 87 Rb gas. We show that the resonant microwave coupling between the 46s and 45p states leads to an Autler-Townes splitting of the EIT resonance. This splitting can be employed to vary the group index by ±10 5 allowing independent control of the propagation of dark state polaritons. We also demonstrate that microwave dressing leads to enhanced interaction effects. In particular, we present evidence for a 1/R 3 energy shift between Rydberg states resonantly coupled by the microwave field and the ensuing breakdown of the pair-wise interaction approximation.
