Opis:: The high resolution spectroscopy of nanometric-thin alkali-vapor layers was made possible through the development of extremely thin cell. We have investigated the behavior of the extremely thin cell fluorescence spectra both experimentally and theoretically. Experiment is performed on the D$\text{}_{2}$ line of Cs-vapor-layer with thickness L=mλ, where m = 0.5, 0.75, 1, 1.25. For open optical transitions, the fluorescence spectra shows narrow dip on the top of the sub-Doppler-width fluorescence profile, at L≥λ. In case of closed transition, an extremely small feature in the fluorescence slightly shifted from its maximum is observed at L =(5/4)λ. The used theoretical model, based on the optical Bloch equations is in qualitative agreement with the experimental observations.

Opis:: We present the first experimental observation of narrow dips in the fluorescence profiles of completely closed hyperfine transitions in Rb vapor at high atomic density, which is attributed to the depolarization of the excited state. Moreover, at low atomic density, a narrow peak on the top of the fluorescence profile is demonstrated, centered at the completely closed transition within the $D_{2}$ line of Cs. Experiments are performed in thin (700 μm) alkali cell by single light beam spectroscopy. The cell is filled with Cs containing a small portion of Rb.

Opis:: The high resolution spectroscopy of nanometric alkali-vapor layers has been made possible through the development of extremely thin cell. We present a detailed comparison of the fluorescence profiles amplitude and width, obtained in the extremely thin cell, both theoretically and experimentally. Experiments are performed on the D_{2} line of Cs-vapor layer with thickness L = mλ, where m = 0.5, 0.75, 1, 1.25. The enhancement rate of the transition profiles width is not growing monotonously, but it is larger for L varying in the interval from L = 0.75 λ to L = λ than that varying in the interval from L = λ to L = 1.25 λ. The used theoretical model, based on the optical Bloch equations is in qualitative agreement with the experimental observations.
