Coherent beam doesn't change things but details depend on what beam's for, e.g. driving normal RO w/1 atom leads to photon subtracted coherent state (which is still non-classical). Details of cavity matter, but solid angle isn't most important factor. High Q cavity close to atom resonance gives strong coupling which greatly enhances spontaneous emission (SE) rate into that single mode via Purcell effect. The smaller SE rates into other modes is source of decoherence & damping of RO. | |

And also what if the solid angle subtended by the mirrors on the atom is very small, then the spontaneously emitted photon will be lost most of the times. | |
