Efficient coupling between light and matter is desirable for quantum information applications as well as for fundamental research. Here we report about the progress of our experiment that aims at efficient excitation of a single ion by a single photon in free space. We discuss several important aspects of the experiment which include: the development and testing of an optically highly accessible ion trap, the choice of the ionic species, the generation of the optimum dipolar radiation pattern by use of a parabolic mirror as well as the correction of the interferometrically measured aberrations of a parabolic mirror.
