本文对椭圆偏振激光脉冲诱导氖原子强场双电离的关联电子动量谱进行了实验和理论研究。一个显着的不对称性的电子动量分布沿着主极化轴的报告。这种不对称性敏感地依赖于激光椭圆率。使用一个三维的半经典模型，我们属性这种不对称模式的椭圆度依赖的概率分布的时间的椭圆度。我们的工作表明，通过简单地改变椭圆率，相关的电子发射可以二维控制，并可以在一个子周期的时间尺度上操纵的电子轨迹。
We present a joint experimental and theoretical investigation of the correlated electron momentum spectra from strong-field double ionization of neon induced by elliptically polarized laser pulses. A significant asymmetry of the electron momentum distributions along the major polarization axis is reported. This asymmetry depends sensitively on the laser ellipticity. Using a three-dimensional semiclassical model, we attribute this asymmetry pattern to the ellipticity-dependent probability distributions of recollision time. Our work demonstrates that, by simply varying the ellipticity, the correlated electron emission can be two-dimensionally controlled and the recolliding electron trajectories can be steered on a subcycle time scale.
