摘　　要：通过考察单光子Jaynes-Cummings(J-C)模型和非简并双光子J-C模型中原子偶极压缩和光场压缩随时间演化的规律,研究了原子偶极压缩与光场压缩之间的关系,给出了处于偶极压缩状态的原子辐射压缩光的条件,并讨论了原子压缩分量与光场压缩分量之间相互转化的特征,指出了原子-光场间的双光子耦合系统比单光子耦合系统更有利于制备压缩程度深的压缩光.By means or investigating the time evolution of the atomic dipole squeezing and the field squeezing in the one-photon Jaynes-Cummings model and the nondege-nerate two-photon Jaynes-Cummings model, the relations between atomic dipole squeezing and squeezing in the radiating field are examined. The conditions under which the atom in atomic dipole squeezed state can radiate squeezed light are presented. The properties of the squeezing transformation between atomic dipole quadrature components and field quadrature components are also discussed. And in the atom-field coupling system, the two-photon transtion processes in producing squeezed light are superior to the one-photon transition processes.
