| 摘 要： | 研究了光场与A-型三能级原子依赖强度耦合系统光场的压缩特性,讨论了单光子跃迁失谐量和初始光场压缩因子对光场压缩的影响.研究结果表明:光场与原子单光子跃迁失谐量和初始光场的压缩因子对光场的压缩特性具有非常重要的影响,在失谐量较大的情况下光场呈连续压缩状态,失谐量较小时则表现为周期性压缩.压缩因子r的大小也影响光场的压缩情况,r越大光场的压缩越深.

| Abstract: | The squeezing properties of light field interacting with the A-type three level atom via intensity-dependent coupling are studied and the influences of detuning between the atomic transition frequency and the light frequency in single-photon process and the initial squeezing of light on the light squeezing are discussed emphatically. The results show that both the detuning and the initial squeezing of light strongly influence the squeezing of field. The light squeezing remains continuous if the detuning is big enough, but if the detuning is little the light field will be squeezed periodically. The bigger the initial squeezing factor of light is, the deeper the light squeezing is. |
