Coherent optical resonances formation in micro- and nano- metric thin cells containing atomic vapor of metal: EIT- and N-resonances
The results of the peculiarities of the electromagnetically induced transparency (EIT) resonance formation when the atomic vapor column is vary in the range of 100 nm up to 1 mm will be presented. Particularly, use of 30-μm-thin cell filled with the Rb and neon gas allows us to reveal that the Rb atoms enter the hyperfine Paschen–Back regime in magnetic fields of >1500 G .
The results on the N –type resonances excited in the Rb atoms confined in a thin cells with variable thickness from 1 μm to 1 mm for the cases of a pure Rb atomic vapor and of a vapor with neon gas admission will be presented. Good contrast and narrow linewidth obtained in 40-μm-thin cell was exploited to study the splitting of the N-type resonance in a magnetic field of up to 2200 G .
Comparison between the EIT- and N-type resonances will be presented.
