摘要
本文建立了“q模腔场-两原子”系统的任意N∑光子相互作用模型，利用这一模型研究了两个偶极一偶极力关联的等同双能级原子与q模腔场任意N∑光子．共振相互作用的辐射谱．对q模腔场分别处于不同数态：即q模腔场均为真空场、q模腔场均为强场、1模为真空场（q－1）模为强场、q0模为真空场（q—q0）模为强场、以及（q—1）模为真空场1模为强场时辐射谱的结构持征及物理特性进行了详细分析，揭示出“q模腔场-两原子”系统任意N∑光子共振相互作用辐射谱的一般特征．现有文献报道，仅仅是本文的普遍性结果在各种不同情况下的特例．
In this paper, the interaction model of q-modes cavity fields-two atoms'system interactingthrough any N∑-photon process has been constructed,and the emission spectrum for a pair of dipoledipole coupled identical two-level atoms interacting with q-mode cavity fields resonantly through anyN∑-photon process has been studied,which are based upon the model mentioned above. The structurefeatures and physical properties of the spectrum are discussed in detail when the q-modes cavity fieldsare initially in various number states. such as all the q-modes are initially in vaccum-field, or inintense-field, one mode in the vaccum - field while the other (q-1) modes in intense-field, q0 modes invaccum-field while the other (qq0)modes in intensei-field,and (q-1)modes in vaccum-field while theother one in the intense-field and so on. Tile general characteristcis of the spectra are thereforerevealed. And the result of all the references that were reported in recent years appeared to be onlyspecific examples of our paper under different conditions.
