利用经典系综模型,系统研究了不同载波包络相位(Carrier-envelopphase,CEP)下少光周期的中红外激光脉冲驱动的Xe原子非次序双电离,并比较了近红外激光脉冲的情况。结果表明,中红外激光脉冲下,随CEP的增加,关联电子沿激光偏振方向的动量谱由分布在第一、二、四象限的弧形结构转变到主要分布在第一、三象限的弧形结构。而近红外激光脉冲下,关联电子动量谱由主要分布在第一、三象限的V型结构转变到主要分布在第一象限的V型结构。反演分析发现,中红外激光脉冲下,NSDI主要以直接碰撞电离机制主导,碰撞时间主要由位于激光场峰值附近的P1峰和位于激光场零点附近的P2峰贡献,P1峰导致关联电子动量谱在第一、二、四象限的弧形结构,P2峰导致关联电子动量谱在第一、三象限的弧形结构。进一步研究发现,对于中红外激光脉冲,根据双电离与碰撞之间的时间延迟进一步把NSDI事件分开,发现即使对于直接碰撞电离机制,不同的时间延迟范围内,电子关联特性仍呈现出不同的行为。
