Abstract
In principle, the optical forces experienced by ions are of the same origin as for the case of neutral atoms. This is due to the fact that the light shift responsible for the optical potential stems from the coupling of the light field to the outer electron of the atoms and not to the electric charge. Thus, in a field-free environment, the effective potentials generated by an optical field for an ion and a neutral atom of the same polarizability and energy level structure would be identical. So in order to obtain a trapping potential for an ion, we would only have to replace the potential generated by an external electric quadrupole field modulated at radiofrequency with suitable optical fields, e.g. a red-detuned Gaussian beam focused on the ion. In the following, we will discuss the complications arising from the interaction of ions with ambient electric fields, the consequential prerequisites, and experimental techniques for carrying out optical ion trapping experiments.
