| 摘 要： | 运用经典理论方法，并采用辛算法数值求解了双色激光场作用下1维共线氢分子离子(H2+)的哈密顿正则方程，得到了氢分子离子在激光场下的经典轨迹。计算了单色场和双色场下氢分子离子(H2+)的存活几率、电离几率、解离几率、库仑爆炸几率随时间的演化，分析了双色场的相位、强度、强度比及倍频的变化对氢分子离子动力学行为的影响,并给出了相应的物理解释。

| Abstract: | The dynamics of a one-dimensional hydrogen molecule ion(H_2~ ) in two-color intense laser field was studied.The classical trajectories were obtained by solving numerically the classical Hamiltonian equations.Based on the classical theory and symplectic algorithm,the probabilities of survival,ionization,dissociation and Coulomb explosion were implemented,meanwhile the influence of the intensity of the laser field on this diatomic ion model was evaluated.The classical dynamics caused by the phase-difference,the laser intensity-difference,and the frequency-difference between the two laser pulses were illustrated and some physical explanations were given. |
