多能级原子的倏逝态wave diffraction
Evanescent wave diffraction of multi-level atoms
摘要：
通过数值求解含时薛定谔方程，模拟了多能级原子在倏逝波反射式衍射光栅中的衍射。我们能够解释在亚稳态氖实验中观察到的衍射现象。这在两能级原子模型中是不可能的。多级模型预测衍射对激光偏振和入射和反射激光束的强度比的敏感依赖性。
英文摘要：
Diffraction of multi-level atoms by an evanescent wave reflective diffraction grating is modeled by numerically solving the time-dependent Schrödinger equation. We are able to explain the diffraction observed in experiments with metastable Neon. This is not possible using a two-level atom model. The multi-level model predicts sensitive dependence of diffraction on the laser polarization and on the intensity ratio of incoming and reflected laser beams.
