TL;DR: In the three-level medium a (3) may be generated by atomic coherence effects which involve negligible saturation and are essentially "spontaneous-emission-free," which offers considerable experimental advantages for the generation of squeezed states of light via four-wave mixing or optical bistability.

TL;DR: In this paper, the interaction of a three-level atomic medium with two degenerate sublevels in the ground state with a coherent radiation field in a ring cavity is investigated, and the authors pay specific attention to atomic coherence within the ground-state doublet and introduce separate decay rates for the groundstate coherence and the population difference.
Abstract: The interaction of a three-level atomic medium with two degenerate sublevels in the ground state with a coherent radiation field in a ring cavity is investigated. We pay specific attention to atomic coherence within the ground-state doublet, and introduce separate decay rates for the ground-state coherence and the population difference. If the atomic density exceeds a critical value, the system exhibits “symmetric bistability”. In addition, in certain regions of parameter space we find symmetry-breaking branches, yielding optical multistability. We propose physical mechanisms for the symmetric as well as for the symmetry-breaking instability.
