CAVITY FIELD SPECTRA OF AN ATOM INTERACTING WITH TWO-MODE FIELD THROUGH RAMAN PROCESS 

研究了在高Q腔内二能级原子与双模量子化光场发生双光子共振喇曼相互作用过程的腔场谱 .发现原子初态的不同不改变腔场谱结构的基本特征 .两模光场初态均为光子数态或均为相干态时 ,每模腔场谱一般都为双线结构 ,两条谱线的频差与另一模初始场强大致成正比 。

The cavity field spectra of a two level atom interacting with two-mode field through Raman process are investigated. It is shown that the basic features of the spectra is unchanged whether the atom is in the high or low level state initially. Symmetrical two-peak structure appears in the spectrum for each mode when the initial fields are both in the pure number states or both in the coherent states. The split of the two peaks is proportional to the field intensity of the other mode.
