“…The 10 4 order of magnitude difference between the calculated oscillator strengths is a property that is unique to cesium when compared with the other alkali-metal atoms. The divergence of the principal-series doublet (6S 1/2 → nP 3/2,1/2 ) oscillator strength ratio for large n is a well-known phenomenon that arises with the inclusion of spin-orbit effects and the core polarizability [16][17][18][19]. This result favors exciting to nP 3/2 states in the interest of reducing laser power requirements.…”

We explore a single-photon approach to Rydberg state excitation and Rydberg blockade. Using detailed theoretical models, we show the feasibility of direct excitation, predict the effect of background electric fields, and calculate the required interatomic distance to observe Rydberg blockade. We then measure and control the electric field environment to enable coherent control of Rydberg states. With this coherent control, we demonstrate Rydberg blockade of two atoms separated by 6.6(3) µm. When compared with the more common two-photon excitation method, this singlephoton approach is advantageous because it eliminates channels for decoherence through photon scattering and ac Stark shifts from the intermediate state while moderately increasing Doppler sensitivity.

“…The experiment was initially implemented in view of getting atomic reference lines in the course of a selective reflection experiment [2]. The third-resonance line has an oscillator strength of ∼10 −3 (at 388 nm), the 389-nm line being much weaker (3×10 −4 [3]) due to the well-known Fermi anomaly of Cs [4]. The lifetime of Cs (8P) (∼265 ns) [5] is governed by a variety of decay channels, making the natural width of the transition as large as ∼0.…”

Extra sub-Doppler lines in the vicinity of the third-resonance 6S-8Ptransition of atomic Cs attributed to optically induced Cs dimers

We report on the observation of additional sub-Doppler lines in a saturated absorption experiment when exploring the vicinity of the 6S 1/2 − 8P 3/2 transition of Cs (λ = 388 nm). These additional lines are observed only under a relatively strong irradiation of both the pump and the probe beams. Extra narrow lines are also observed in copropagating nonlinear spectroscopy, and around the lines of the V-type three-level system 8P 3/2 − 6S 1/2 − 8P 1/2 (λ 1 = 388 nm, λ 2 = 389 nm). We attribute theses additional lines to a probing of high-lying molecular cesium, produced as a result of the optical excitation of Cs atoms, as the low Cs atom density ( 10 12 cm −3 ) is unable to populate significantly the dimer states in the condition of thermal equilibrium.
