摘要
The correlated electron dynamics of asymmetric molecules driven by orthogonal two-color laser pulse is investigated by classical ensemble method. It is found that the patterns of correlated momentum distributions depend sensitively on the relative phase as well as the intensity ratio of the two-color fields. Moreover, the affection of intensity ratio on the correlated momentum distributions changes with relative phase. The results above are explained by the back analysis of recollision time and recollision angle of double ionization trajectories. (C) 2012 Elsevier B.V. All rights reserved.
