我们预测了高场原子双电离中新的脉冲末端行为。计算了短脉冲强激光中原子电子的运动轨迹，证实了我们的椭圆偏振分析。我们展示了一个四带结构的离子动量分布在不同的椭圆度，并预测，顺序和非顺序双电离可以干净地区分椭圆极化。
We predict new end-of-pulse behavior in high-field atomic double ionization. Calculations of atomic electron trajectories in short intense laser pulses confirm our analysis of elliptical polarization. We exhibit a four-band structure in ion momentum distributions under various ellipticities, and predict that sequential and nonsequential double ionization can be cleanly distinguished under elliptical polarization.
