利用数值求解含时薛定谔方程和强场近似理论研究了反向旋转双色椭偏光场中氩原子隧穿电离电子的干涉. 固定两脉冲的椭偏率均为0.3, 当两椭偏场的相对相位为0.25π时, 光电子动量谱中周期内干涉、叉状全息干涉和弧形全息干涉相互重叠. 当两椭偏场的相对相位为0时, 光电子动量谱中弧形全息干涉消除, 并且周期内干涉和叉状全息干涉被彻底分离到动量谱的左右部分, 从而得到一个在空间上独立的叉状全息干涉条纹. 进一步研究表明, 通过改变两椭偏光场的椭偏率还可以增强或抑制该独立叉状全息干涉条纹. 这为干涉条纹的控制和分离提供了一个有效的手段, 同时也有利于从全息干涉条纹中提取靶材结构信息和电子超快动力学信息.In this paper, photoelectron interference in tunneling ionization of atoms by counter-rotating two-color elliptically polarized (TCEP) laser fields are investigated by numerically solving the two-dimensional time-dependent Schrödinger equation (TDSE) and strong field approximation (SFA). When the ellipticities of the two pulses are both 0.3, for a relative phase of 0.25π, the intracycle interference, fork-like holographic interference and arc-like holographic interference in the photoelectron momentum distribution overlap with each other. For a relative phase of 0, the arc-like holographic interference disappears and the intracycle interference and fork-like holographic interference are fully separated into the –px direction and the +px direction. Furthermore, the independent fork-like holographic interference can be enhanced or suppressed by changing the ellipticities of the two pulses. This provides an efficient tool for controlling and separating the interference structures in the photoelectron momentum distribution, which facilitates extracting the information about the target structure and the photoelectron ultrafast dynamics in strong fields.
