Abstract
利用全量子理论，研究 NCS(the number-chaotic state)态光场与多光子跃迁运动二能级原子相互作用过程中的粒子布局数反转问题。分析了原子初态、场模结构参数、热平均光子数、数态光子数、跃迁光子数等参量对系统粒子布局数反转的影响，结果表明：由于原子的运动，使粒子布局数反转表现出不同的周期振荡规律；跃迁光子数取不同值时，系统粒子布局数反转呈现不同的规律。
The atomic inversion evolution in a system which is composed of a multi-photon transition moving two-level atom interacting with the number-chaotic state is studied by means of the full quantum theory.The influences of the atomic initial state,field-mode structure parameter,the average photon num-ber of the chaotic state,the photon number of the number state and the values of the transitional photon number are also analysed in this paper.The results show that the atomic motion will make the particle dis-tribution inversion appear different periodic oscillation rules.The particle distribution inversion presents different patterns because of the parity of transition photon number.
