Control of molecule dynamics by means of multimode laser field
Keywords: analytical solution, multilevel model, transition between non-adjacent levels,
multifrequency field, selective excitation
A number of new analytical solutions for equations of vibrational dynamics of molecules in multifrequency laser field has been obtained in this work. The solutions are the multiparametric wave functions derived by original integral transforms. The parameters are defined by the spectroscopic characteristics of model multilevel quantum systems and multifrequency field ones. The field and spectroscopic characteristics can be changed independently. Variation of the field characteristics allows analyzing manifold dynamics of the molecule excitation.
As a result of theoretical research, new conditions of the effective vibrational excitation of molecular systems by specially selected multifrequency radiation have been revealed. Some recommendations for the optimal choice of multifrequency field characteristics at fast preparation of the necessary molecular excitation states have been given.
