Abstract

The manipulation of atoms and molecules is one of the most important and intriguing subjects in modern physics, chemistry, and biology. The control of the spatial orientation of molecules is especially important for studies of orientational effects in chemical reactions [1]. The alignment of neutral molecules by a strong linearly polarized laser field has already been demonstrated [2,3]. At present, electric hexapole focusing and strong static electric field orientation are employed to control the orientation of polar molecules. However, electric hexapole focusing works only for symmetric top molecules and strong static electric field orientation is effective only for certain molecules possessing large permanent dipole moments. The realization of molecular orientation to arrange any polar molecules in a “head-versus-tail” order is a next challenging subject.
