文摘A classical ensemble method is used to investigate nonsequential double ionization（NSDI） of Ar atoms irradiated by linearly polarized few-cycle laser pulses. The correlated-electron momentum distribution（CMD） exhibits a strong dependence on the carrier-envelope phase（CEP）. When the pulse duration is four cycles, the CMD shows a cross-like structure, which is consistent with experimental results. The CEP dependence is more notable when the laser pulse duration is decreased to two cycles and a special L-shaped structure appears in CMD. Recollision time of returning electrons greatly depends on CEP, which plays a significant role in accounting for the appearance of this structure.
