摘要
本文研究了双原子与单模光场拉曼相互作用系统中， 在光场和原子具有不同的耦合并计及原子间偶极－ 偶极相互作用情况下，光场相位的演化特性。给出了初始为极弱和极强相干态光场时光场相位概率分布、相位算符期望值及相位涨落的解析表达式， 并讨论了双原子与腔场之间耦合常数的相对大小及原子偶极相互作用强度对辐射场相位统计性质的影响。
The properties of the phase evolution in the system of Raman interaction between two atoms and a single mode cavity field are studied in the cases of two atoms with dipole dipole interaction coupling to the field with different constants. The phase probability distribution, the expectation values of phase operator and the phase fluctuation in an initial coherent field with strong and very weak intensity are given respectively. The influence of the relative value of two atom field coupling constants and also that of atomic dipole dipole interaction on the statistical phase properties of light are discussed.
