主　　题：harmonic generation channel-interference bound states potential models 

摘      要：We calculated the power spectra of harmonic generation for the one-electron system in 7 potential models with different quantities of bound states. It indicates that the increase of weakly bound states has little influence on the enhancement of harmonic intensity in the high-order region. Further research on the so-called channel-interference of harmonic generation is obtained, which shows that the channel-interference of harmonic generation exists for all potential models. Therefore, channel-interference maybe a ubiquitous phenomenon for one-electron system driven by bichromatic field, and the increase of bound states can augment the effect of channel-interference. Our calculations can provide some insight on the mechanism of channel-interference and harmonic generation.
