两模微波激射器中三能级原子布居数随时间的演化

在相互作用绘景中,得到了两模微波激射器的腔模与注入其内的Λ型三能级原子构成的相互作用系统的演化算符的矩阵表示,以及该系统的态函数随时间的演化关系,在此基础上导出了原子布居数随时间的演化关系,由此可进一步研究布居数的振荡、反转和捕获等问题.

The time-evolution of the three-level atomic population in a two-mode micromaser

For the system consisting of the cavity modes with an injected Λ-type three level atom in a two-mode micromaser, the matrix form of the evolution operator and the time-evolution of its state are obtained in the interaction picuture. The time-evolution of the atomic population is derived on the basis of the above investigation, which is useful for further research on the population oscillating and inversion and trapping and etc.
