【摘要】 研究了类克尔介质中虚光场效应对受激三能级原子的光子统计演化性质的影响。结果表明: 虚光场效应导致了受激辐射场的光子统计演化中出现了量子噪声, 量子噪声随光场频率ω的增大而减小, 当ω增大到一定值时, 量子噪声几乎消失, 原子-场耦合系数λ的增加使光子统计演化的拉比振荡的振幅加大、频率变快; 而介质-场耦合系数μ的增加使光子统计演化拉比振荡的振幅变小、频率变慢更多还原

【Abstract】 The effect of virtual photon field in the Kerr like medium on the photon statistical evolution of one excited three level atom was investigated. The results show that the quantum noise of the photon statistical evolution is caused by the virtual photon field, the quantum noise becomes weak gradually while ω increases, and disappears while ω approaches threshold. The amplitude of Rabi oscillation increases and the frequency becomes higher while λ increases, and the quantum noise simultaneously becomes strong. On the other hand, the amplitude decreases and the frequency becomes slower while μ increases, and the quantum noise simultaneously becomes weak.更多还原
