Theoretical Investigation of the Faraday Rotation Effect in Atomic Alkali Nano-Layers

Аннотация

Theoretical studies of the Faraday rotation (FR) effect in alkali vapors contained in extremely thin cells are presented. It is shown that the spectra of the FR signal are well frequency resolved despite the huge number of atomic transitions. This allows one to study the evolution of the Cs D₁ (λ = 895 nm) line hyperfine structure of F_g = 4 → F_e = 3, 4 atomic transitions in magnetic fields. The presented theoretical model predicts the coherent Dicke narrowing effect and its revival with a periodicity Δ_L = λ. The practical applications of the FR are noted.
