摘要/Abstract

摘要： 为获得两个非等同二能级原子与双模光场相互作用过程的腔场谱特性，通过求解本征方程导出了双模初始光场处于任意强度的热光场时腔场谱的计算公式，给出了数值计算结果．文中还讨论了相对耦合常数和初始场强对腔场谱的影响．发现在相对耦合常数为零且初始场较弱的条件下，两模腔场谱均为双峰结构；随着相对耦合常数的增大，双峰逐渐靠近，到相对耦合常数为1时，每模腔场谱都合并为单峰．随着一模光场平均光子数的增大，本模腔场谱双峰之间的距离减小，而另一模腔场谱双峰之间的距离增大、

Abstract:

In order to obtain the cavity field spectra of two different atoms interacting with a two.mode field.the ex-pression of the cavity field spectra in an initial thermal field with random intensity is derived by solving the eigen equation,and some numerical results are presented.Moreover,the effects of the relative coupling constant and the initial field intensity on the spectrum structure al"e discussed.It is found that(1)a two-peak structure appears for
each mode spectrum when the relative coupling constant is naught and the initial field is relatively weak;(2)the two peaks gradually draw close to each other with the increase in relative coupling constant;(3)each mode spec-trum appears as a single peak when the relative coupling constant achieves 1;and(4)when the average photon number of one mode increases,the distance between the pair peaks of this mode decreases,while that of the other
mode increases.
