摘要 应用经典理论方法,采用辛算法,数值求解双色激光场作用下的一维共线氢分子的哈密顿正则方程,得到氢分子在激光场作用下的经典轨迹,并计算H2+,H22+,H,H+等产物的产生概率随时间的演化,分析了双色场的光强、倍频、相位的变化对氢分子动力学性质的影响并给出相关的物理解释. Dynamics of one-dimensional hydrogen molecule in two-color intense laser field is studied with classical theory and symplectic algorithm. Classical trajectories are obtained by solving Hamiltonian equations numerically. Probabilities of H2^+ , H2^2+ , H, H ^+ are evaluated. Classical dynamics caused by laser intensity, frequency, and phase are illustrated and explained.
