摘要
研究了与双模纠缠相干光场作用的Ξ型三能级原子的偶极振幅平方压缩效应,分析了双模纠缠相干光场的纠缠程度、原子的基态概率幅、失谐量、平均光子数以及光场与原子的耦合常数对原子的偶极振幅平方压缩的影响;结果表明,此压缩效应与双模纠缠光场的纠缠程度、失谐量、平均光子数、光场与原子的耦合常数和原子初态相关联。
The atomic dipole amplitude-squared squeezing effects ot a Ξ-type three-iewl ting with two-mode entangled coherent states are investigated. The effects of the degree of entanglement of the two-mode entangled coherent states, the ground state probability amplitude of the atomic initial state, the detuning, the mean photon number and the atom-field coupling constant on the atomic dipole amplitude-squared squeezing are analyzed. The results indicate that the light squeezing effects depend on the degree of entanglement of the two-mode entangled coherent optical fields, the detuning, the mean photon numbers, the atom-field coupling constant and the atomic initial state.
