| 摘 要： | 研究了处于双模腔中的两个非等同二能级原子与叠加态光场的拉曼相互作用,推导出了两模光场均处于光子数态和任意叠加态时腔场谱的计算公式,给出了两模初始场为相干态和压缩真空态时谱结构的数值结果,讨论了相对耦合常数R=g2/g1和初始场强对腔场谱的影响.发现腔场谱结构不仅与初始场强有关,还随初始场光子数分布的变化而改变.

| Abstract: | The Raman interacting of two different atoms with two-mode cavity fields is studied. the cavity field spectrum expression of the system with the fields in superposition state is given out. Some numerical results for the fields in coherent states, and squeezed vacuum st ates are presented. The effects of relative coupling constant R=g_2/g_1 on the spe ctrum structure are discussed. It is found that the spectra are influenced sensitively by the initi al field intensity and the photon number distribution. |
