线性偏振双色场下阈值以下非顺序双电离I：对称性与主导性
摘要
我们研究了利用线性偏振双色场引起的非顺序双电离，聚焦于重碰撞-激发随随后电离（RESI）机制。我们运用强场近似，评估了场的对称性如何影响主要事件。 Furthermore, we show that, by manipulating the field parameters such as the field frequencies and relative phase between the two driving waves, one can influence the correlated electron-momentum distributions. Specific features of a linearly polarized bichromatic field are that the momentum distributions of the second electron are no longer centered around vanishing momenta and that there may be more than one ionization event per half cycle. This can be used to confine the RESI distributions to specific momentum regions and to determine a hierarchy of parameters that make an event dominant.
