【Abstract】 We investigate the free-free transition in the presence of the resonant bichromatic laser field. The target atom is described by the three-level model and the rotating wave approximation. The differential cross section for a multi-channel collision is derived. The calculations show that excitation collision has quite small contribution to the whole collision pr ocesses.更多还原
