Coherent Population Trapping Resonances in Cs Atomic Vapor Layers of Micrometric Thickness

Figure 6

Illustration of the population distribution between the Zeeman sublevels of the ground level 𝐹_𝑔=4 (a) and of the excited level 𝐹_𝑒=5 (b) for the 𝐹_𝑔=4→𝐹_𝑒=5 transition, without depolarization factors influencing the excited level. The ground-level population is mainly accumulated on the sublevels 𝑚_𝐹=0, ±1, having the highest excitation probabilities (Clebsch-Gordon coefficients).
