| Abstract: | Optical-bistability conditions for a thin (smaller than the wavelength of the acting laser radiation) surface layer of resonance
atoms are calculated with allowance for the influence of the polarizing fields of transitions adjacent to the resonance one
and allowed in the electrodipole approximation on the transmissivity of the medium of the layer. It is noted that the change
in the threshold bistability characteristics is due to the influence of the self-modulation broadening of the line of the
laser field occurring in the thin resonancepolarized layer on the effective level of its absorption.
