Abstract: 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+,H22+,H,H+ are evaluated.Classical dynamics caused by laser intensity,frequency,and phase are illustrated and explained.
Key words: two-color intense laser field, hydrogen molecule, classical dynamics, symplectic algorithm
