We examine correlated electron and doubly charged ion momentum spectra from strong field double ionization of neon employing intense elliptically polarized laser pulses. An ellipticity-dependent asymmetry of correlated electron and ion momentum distributions has been observed. Using a 3D semiclassical model, we demonstrate that our observations reflect the subcycle dynamics of the recollision process. Our Letter reveals a general physical picture for recollision impact double ionization with elliptical polarization and demonstrates the possibility of ultrafast control of the recollision dynamics.
我们通过使用强椭圆偏振激光脉冲研究了氖的强场双电离中关联电子和双价离子动量谱。观察到了关联电子和离子动量分布的椭圆偏振依赖性不对称性。使用三维半经典模型，我们证明了我们的观察结果反映了再碰撞过程的亚周期动力学。我们的信件揭示了具有椭圆偏振的再碰撞碰撞双电离的一般物理图景，并证明了对再碰撞动力学进行超快控制的可能性。
