Multiple quantum transitions in optically oriented87Rb vapour

E. Arimondo, R. Corbalán

In an optically pumped 87 Rb vapour, multiple quantum transitions in the ground state Zeeman sublevels are examined as a function of the radiofrequency field intensity. The experimental results are compared with existing theoretical approaches. Good agreement is found, for the resonance shifts, with the theoretical analysis based on the Hamiltonian solution for the atom plus RF field system. A more refined theory must be developed for interpreting line broadening results.

Investigation of Optical Pumping in Cesium Atoms with a Radio-Frequency Field, Using Liouville Equation

Hossein Davoodi Yeganeh, Zahra Shaterzadeh‐Yazdi

Optical pumping is a technique for engineering atomic-sublevel population of desired atoms. We investigate the population evolution of Cesium atoms by employing Liouville equation. For this purpose, we apply a circularly polarized light at a frequency suitable for electronic transition from ground states to excited states and calculate the relaxation rate, repopulation, and population evolution of the Cesium Zeeman sublevels. For engineering the sublevel population after optical pumping, we employ a radiofrequency (RF) field and consider the effect of RF field in Liouville equation. With this approach, we are able to prepare desired distribution of the population in the atomic sublevels with high efficiency, which can be employed in different optical experiments.
