两能级原子在激光衰波场中的共振反射

Resonant Reflection of a Two Level Atom by Evanescent Laser Wave

在共振情况下求解两能级原子在激光衰波场中的薛定谔方程，得到了基态原子反射率Ｒｇ、激发态原子反射率Ｒｅ以及原子总反射率Ｒｔ的解析表达式。然后通过数值计算，详细讨论了Ｒｇ、Ｒｅ、Ｒｔ与拉比频率、原子垂直于靶面方向运动的动能的依赖关系。

The analytical solution for resonant reflection of a two level atom by an evanescent laser wave is presented. Consequently, We numerically calculate and theoretically analyse the atomic reflection coefficient as a function of Rabi frequency and the kinetic energy of the atom moving along the y direction.
