We study the frustrated tunneling ionization (FTI) in counter-rotating and co-rotating circularly polarized two-color (CPTC) laser fields using a classical electron ensemble method. We find that the FTI probability depends sensitively on the relative helicity and the field amplitude ratio of the two-color laser fields. The FTI probability in the counter-rotating CPTC laser fields is three orders higher than that in the co-rotating fields. In the counter-rotating CPTC laser fields, the maximal FTI probability appears at the field amplitude ratio of ∼2.0, while in the co-rotating CPTC laser fields it appears at the ratio of ∼3.6. Tracing the electron trajectories, we find that recollision-assisted recapture plays an important role for the FTI in the CPTC laser fields. We further show that the angular momentum of the Rydberg state from the FTI events can be controlled by changing the field amplitude ratio of the counter-rotating CPTC laser fields, while it is nearly unchanged in the co-rotating CPTC laser fields.

我们使用经典的电子集成方法研究了反向旋转和同向旋转的圆偏振双色（CPTC）激光场中的受挫隧穿电离（FTI）。我们发现FTI概率敏感地取决于双色激光场的相对螺旋度和场振幅比。反向旋转的CPTC激光场中的FTI概率比同向旋转的场中的FTI概率高三个数量级。在反向旋转的CPTC激光场中，最大FTI概率出现在〜2.0的场振幅比上，而在反向旋转的CPTC激光场中，出现在〜3.6的比率。跟踪电子轨迹，我们发现，在CPTC激光场中，碰撞辅助捕获对于FTI起着重要作用。
