    "abstract": "We analyze the above-threshold behavior of a mirrorless parametric oscillator\nbased on resonantly enhanced four wave mixing in a coherently driven dense\natomic vapor. It is shown that, in the ideal limit, an arbitrary small flux of\npump photons is sufficient to reach the oscillator threshold. We demonstrate\nthat due to the large group-velocity delays associated with coherent media, an\nextremely narrow oscillator linewidth is possible, making a narrow-band source\nof non-classical radiation feasible.",
