摘　　要：利用经典理论采用辛算法计算了一维氢分子在超短强激光脉冲作用下的存活、电离、解离和库仑爆炸的动力学行为.研究了在相同波长、不同场强和相同场强、不同波长的动力学几率随时间演化曲线,分析了场强和波长的变化对氢分子动力学行为的影响,并给出了合理的物理解释.The survival,ionization, dissociation and coulomb explode dynamics of a one - dimensional model of molecular hydrogen H2 under intense ultrashort laser pulses were classically simulated. Rates of dynamics have been calculated numerically for the same wavelength and the different intensity, the same intensity and the different wavelength. The classical dynamics caused by the laser different intensity and the different wavelength were illustrated and some physical explanations were given.

关 键 词：超短强激光脉冲 氢分子 辛算法
