| Research Abstract |
We have developed quantum optimal control simulation that can treat nonlinear interactions between a molecule and laser fields.(1)The simulation is applied to the alignment control of a nitrogen molecule. From the power spectrum of the cycle-averaged intensity of the optimal pulse, we have proposed a frequency network mechanism that effectively connects a few lowest rotational states through Raman transitions to achieve a high degree of alignment.(2)In the orientation control of a CO molecule, we have shown the effectiveness of a two-step control, in which an alignment pulse appear prior to an orientation pulse.(3)We further extended the simulation to explicitly include the polarization of a laser pulse. It was applied to the simultaneous rovibrational control with the aim of creating a rovibrational wave packet that cannot be achieved by a linearly polarized pulse.
