摘要：A time-dependent quantum wave-packet method is employed to investigate the rovibrational dynamics of population transfer in the ground electronic state controlled by two-color (omega + 2 omega) pulses analogous to coherently control the processes of ionization and dissociation. The population can be transferred to three target states, vertical bar 4,1 >, vertical bar 0,1 >, and vertical bar 4,0 >, at the same time through the ladder A and multiphoton transitions. With the variation of the relative phase between omega and 2 omega pulses, the population distributions show oscillation behavior with a period of pi. The population variation with relative phase depends on the size of the electric field asymmetry. The probabilities transferred to different target states can be controlled by varying the pulse amplitudes.
