Abstract: Classical trajectories of a diatomic molecule system (CO) in laser fields are calculated in the symplectic scheme. The calculated results are compared with that with Runge-Kutta (R-K) approach. The vibration trajectories, phase trajectories and vibration energy of a diatomic molecule CO are analysed.

Key words: laser fields, heteronuclear diatomic molecule, classical trajectory approach, symplectic scheme
