| 摘 要： | 采用数值计算方法研究了强相干初态光场与级联型三能级原子相互作用中的光子统计演化。结果表明：光子统计演化呈现Rabi型量子崩塌与回复的性质，随着值的不断增大，场与原子的非线性耦合越来越强，重复地出现回复收缩现象。 |
| 关 键 词： | 强场 级联型三能级原子 平均光子数 相互作用 光子统计演化 强相干初态光场 量子光学 |

| Abstract: | In this paper, statistical evolution of the mean photon number in the interaction of a cascade three-level atom with strong coherent field of initial state are studied by numerical calculation. The results show that the statistical evolution of the mean photon number appear Rabi-type quantum collapse and revival properties; with the increasing of the value of n,the nonlinear coupling between the field and the atom is getting stronger and stronger ,and the phenomenon of revival shrink will arise repeatedly. |
| Keywords: | strong coherent field of initial state cascade three-level atom mean photon number |
