| 摘 要： | 利用经典系综模型,研究了正交双色场作用下氢分子非次序双电离中双电离电子的相关特性.结果表明,双电离电子相关动量谱强烈地依赖于正交双色场的相对相位.通过改变正交双色场的相对相位,相关动量可以从反相关模式转变为相关模式.向后分析表明,相关电子动量谱对双色场相对相位的依赖关系起源于碰撞过程中碰撞电子碰撞角和碰撞动量对相对相位...

| Abstract: | By using classical ensemble model,the correlated electron dynamics of H2 driven by orthogonal two-color laser pulses is investigated.it is found that the patterns of correlated momentum distributions depend sensitively on the relative phase of the two-color fields.By changing the relative phase of the two-color field,the electron momentum distributions along the 1 600 nm field change from anticorrclatcd to correlated behavior.Back analysis shows that relative phase dependent recollision angle and recollision momentum is responsible to the dependence of correlated electron momentum distributions on the relative phase. |
