原子的双色干涉稳定化

Two-color interference stabilization of atoms

M. V. Fedorov, N. P. Poluektov

摘要:

干涉稳定的效果被证明是存在于一个系统中的两个原子的水平耦合的强双色激光场,其中的两个频率是接近的双光子拉曼型共振之间的选定的水平,从他们两个的单光子电离的开放通道。我们建议一个实验,其中一个相当显着的(高达90%)抑制电离可以发生,并明确表明稳定的干扰源。对H和He原子作了具体的计算,找到了双色场的最佳参数,讨论了双色场效应的物理机制及其与三能级系统中的LICS和布居囚禁等现象的关系。

英文摘要:

The effect of interference stabilization is shown to exist in a system of two atomic levels coupled by a strong two-color laser field, the two frequencies of which are close to a two-photon Raman-type resonance between the chosen levels, with open channels of one-photon ionization from both of them. We suggest an experiment, in which a rather significant (up to 90%) suppression of ionization can take place and which demonstrates explicitly the interference origin of stabilization. Specific calculations are made for H and He atoms and optimal parameters of a two-color field are found. The physics of the effect and its relation with such well-known phenomena as LICS and population trapping in a three-level system are discussed.
