Optical bistability in the case of broadening by intrinsic pressure
Rautian S. G.
The so-called optical bistability, i.e., the ambiguity of the steady state of the medium in an electromagnetic field, has recently attracted considerable attention. Attention is focused here on the active systems (amplifying medium) and on the passive systems (absorbing medium) (Η. M. Gibbs, Optical Bistability: Controlling Light with Light, Academic Press, Orlando, 1985). In the familiar passive systems the bistability is established by various feedbacks produced by basically complex devices. In contrast, a case is described in the present article, in which the optical bistability "at the atomic level" is attributed to the properties of strictly the absorbing atomic gas.
