摘要:

本文计算了一个含两个较低态和一个由自电离态构成的连续谱或一个具有激光诱导结构的连续谱的类λ模型原子介质的激光修饰电极化率。取决于控制场的强度,可以在小吸收的条件下在窄频率窗口中获得光速的显著降低。一个平滑的过渡之间的情况下,一个平坦的连续和离散的状态作为一个Lambda系统的上状态。

英文摘要:

Electric susceptibility of a laser-dressed atomic medium is calculated for a model Lambda - like system including two lower states and a continuum structured by a presence of an autoionizing state or a continuum with a laser-induced structure. Depending on the strength of a control field it is possible to obtain a significant reduction of the light velocity in a narrow frequency window in the conditions of a small absorption. A smooth transition is shown between the case of a flat continuum and that of a discrete state serving as the upper state of a Lambda system.
