We explain optimal control approaches with the aim of three-dimensional (3D) alignment/orientation of asymmetric molecules by using a combination of dipole and lowest-order-induced dipole interactions, the former of which mixes the rotational states with different parity. The present method enables the numerical design of an optimal temporal structure for the laser pulse including its time-dependent polarization on the basis of the molecular Hamiltonian together with the optimization algorithm. After explaining the theoretical framework, numerical details are examined through a case study of one-dimensional (1D) alignment control that is applied to SO2.
