1. INTRODUCTION
In recent years, a series of studies have been devoted
to the spectroscopy of atomic vapors with the layer
thickness L ~ 101000 m [18]. It is noteworthy that,
even at L ~ 10 m, the sub-Doppler structure manifests
itself under resonance pumping with a single laser
beam [1]; however, for this structure to be revealed, the
laser radiation must be additionally frequency-modu-
lated [13].
Recently, it was shown that the use of an extremely
thin cell (ETC) in which the thickness of the atomic
vapor column is L ~ 150300 nm and an ordinary laser
diode (without frequency modulation) is sufficient for
resolving the hyperfine atomic transitions of the D2 line
of Cs [9]. It is important that the resonance fluorescence
and absorption have linear character (versus the pump-
ing intensity) up to intensities of 100 mW/cm2 [9] and,
