Optical multistability and light self-modulation at double resonance
Averbukh I. Sh. , Kovarskii V. A. , Perel'man N. F.
It is shown that in a system of atoms or molecules, an instability arises in a resonator at double optical resonance conditions, because of the high-frequency Stark effect, caused by the collective field, and this leads to a number of new cooperative threshold optical phenomena.
