| 摘 要： | 本文用量子理论研究激光场与三个原子的相互作用。当初始条件为激光场中有N个光子,而三个原子都处于高能级时,得到了光子数和原子状态各自随时间的变化关系。光子数很大时,量子理论结果与半经典理论结果是一致的。

| Abstract: | In this paper, we give the quantum theory of the interaction between a single -mode laser field and atoms. The interaction between the laser field and three two-level atoms are studied. When the initial state consists of N photons and three atoms at their higher levels, the time evolution of the photon number, as well as the motion of atoms, are obtained. In the case when the number of photons are very large, the result obtained in quantum theory consists with the result obtained in semiclassical theory. |
