【摘要】 利用全量子理论,研究了非旋波近似下单模光场与V型三能级原子依赖强度耦合的相互作用系统中光场的压缩效应.结果表明:光场的压缩依赖于系统的本身性质,而虚光子过程使光场的压缩程度明显加强并产生量子噪声,其大小依赖于初始场平均光子数和光场频率ω,且与原子-光场耦合强度g有关.更多还原

【Abstract】 The time evolution of light squeezing in the intensity-dependent coupling interaction between light field with V-type three-level atom is studied by means of the quantum theory without rotating wave approximation. The result indicate that the light squeezing relates to the properties of the system, Moreover , the squeezing of light is strengthened and the quantum chaos caused by the virtual-photon process depend on the initial state parameters of the system:、ω and g.更多还原
