从数值计算和实验结果可知，隧道电离产生的里德堡态（激发中性原子）的比例随着激光椭圆度的增加而急剧下降。我们提出了一种方法来分析这种依赖于椭圆率，推导出的里德堡态的概率分布，与最近的实验[1]和数值计算结果密切一致。特别是，与现有的提出的机制[1]和一般的预期相矛盾，我们的结果表明，里德堡产额对激光椭圆率的依赖性不是由再散射过程引起的。相反，我们表明，大多数里德伯电子从来没有回到电离后的出口点附近，并最终相对远离原子（相比出口点）后，激光脉冲已经通过。我们还提出了实验数据，揭示了一个分叉，对应于一个截止Rydberg代，并提出了一个解析推导与微扰包含的Coloumb力。[1]T.

英文摘要：
It is well-known from numerical and experimental results that the fraction of Rydberg states (excited neutral atoms) created by tunnel ionization declines dramatically with increasing ellipticity of laser light. We present a method to analyze this dependence on ellipticity, deriving a probability distribution of Rydberg states that agrees closely with recent experimental [1] and numerical results. In particular, contradicting the existing proposed mechanism [1] and general expectations, our results indicate that the dependence of Rydberg yield on laser ellipticity is not caused by a rescattering process. Rather, we show that most Rydberg electrons never come back to the vicinity of the exit point after ionization, and end up relatively far from the atom (compared to the exit point) after the laser pulse has passed. We also present experimental data revealing a bifurcation that corresponds to a cut-off in Rydberg generation, and present an analytic derivation with a perturbative inclusion of the Coloumb force.
