Abstract:The population transfer controlled by fundamental, 2nd-harmonic and 3rd-harmonic pulses is investigated by using the time-dependent quantum wave packet method. By varying the phase phi(1) of the fundamental pulse, it can be coherent with the 2nd-harmonic and 3rd-harmonic pulses. Compared with two harmonic pulses, the phase phi(1) in three harmonic pulses is more efficient in controlling population transfer. Molecular orientation can be controlled by the phases of the three pulses. The value of molecular orientation mainly depends on the phase coherence between the fundamental and 2nd-harmonic pulses.
