Polarization-dependent optical pumping for the laser selection of Zeeman-states in cesium fountain

This paper presents an experimental and theoretical analysis of a possible scheme to realize of optical pumping in the ground state (F = 3) of the cold ¹³³Cs atoms in atomic fountain. The efficiency of the population for the state sub-level F = 3,MF = 0 build up is calculated for two limiting cases of the optical pumping : F = 3 = F´= 2 and F = 3 = F´= 3. This analysis takes into account the hyperfine structures of the energy levels for the ground 6²S_1/2(F = 3) and excited states 6²P_3/2(F´= 2), 6²P_3/2(F´= 3) of cesium atoms.
