原子相干性对V型三能级原子自发辐射的影响

EFFECTS OF THE ATOMIC COHERENCE ON THE SPONTANEOUS EMISSION OF A V-TYPE THREE LEVEL ATOM

本文分别就两种模型 ,即三能级原子与单模场和双模场的 V型相互作用 ,研究了原子相干性对原子自发辐射的影响 .发现在单模情况 ,原子相干性导致原子自发辐射的消除 ;而在双模情况 ,两个跃迁通道的自发辐射是相互独立的 ,原子相干性不导致原子自发辐射的消除 .

The effects of atomic coherence on the spontaneous emission of a three level atom interacting via the V configuration with a one mode cavity field and with a two mode cavity field are studied,respectively.It is shown that the atomic coherence leads to the elimination of spontaneous emission in the one mode case,but do not in the two mode case.
