Cavity field spectra of two different atoms interacting with a two-mode field through Raman process

研究了非等同双原子与双模腔场拉曼相互作用模型的腔场谱 ,分析了谱结构随原子与腔场相对耦合常数R =g2 g1 的变化规律 ,发现R对真空场、弱场、强场谱结构都有不同程度的影响 .当R =1或R =0时 ,一般呈现简并的谱结构 ,而当R介于 0与 1之间时 ,腔场谱一般呈现复杂的非对称多峰结构 .同时还发现 ,当R固定不变时 。

The cavity field spectra of two different atoms interacting with two-mode fields through Raman process are studied.The effects of relative coupling constant R=g 2/g 1 on the spectrum structure are discussed.It is found that R plays a different role in the syectrum for vacuum,weak or strong initial field.Degenerate spectrum structure appears usually for R=1 or R=0.A complicated asymmetric multi-peak structure appears when R is between 0 and 1.When the field of upper frequency mode is vacuum,its spectrum is influenced sensitively by the field intensity of the other mode for fixed R.
