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_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.
