多光子跃迁下Glauber-Lanchs态与运动二能级原子相互作用系统的粒子布局数反转
|
摘要
利用全量子理论,研究了多光子跃迁下Glauber-Lanchs态光场与运动二能级原子相互作用系统的粒子布局数反转.讨论了原子的初始状态、热平均光子数、场模结构参数、相干平均光子数、跃迁光子数对系统粒子布局数反转的影响.结果表明:场模结构参数影响系统粒子布局数反转的振荡周期及振幅大小;原子初始状态、热平均光子数影响粒子布局数反转的振荡幅度;相干平均光子数及跃迁光子数选取不同,系统量子态的原子布局数反转表现出不同的规律.
The full quantum theory was applied to study the population inversion of a moving two-level atom interacting with a Glauber-Lanchs state light via a multi-photon transition in the research.The influence of atomic initial state and the parameters,including field-mode structure parameter,the average photon number of the chaotic state, the mean number of the coherent photons and transitional photon number on the atomic inversion of the system were analyzed.The results revealed that the field-mode structure parameter affected the oscillation period and amplitude of the inversion.The atomic initial state and average photon number of the chaotic state were related to the oscillation amplitude of the inversion.In the case that different mean number of the coherent photons and transitional photon number were selected,different patterns of the atomic inversion of the system were exhibited.
