Efficient photon-atom interaction is essential for quantum communication protocols. We aspire to a coupling strength close to unity for interfacing the free-space light field with a single trapped Ytterbium ion. To this end we trap the ion in the focal point of a deep parabolic mirror allowing illumination from nearly the complete solid angle [1]. The mirror converts a properly shaped incident plane wave into an inwards running dipole wave matching the dipole properties of the atomic transition [2]. Absorption experiments require additional temporal shaping of the incident light [2,3].
We present spatial and temporal pulse shaping at the cooling wavelengths of Yb+ and Yb2+ (370nm and 252nm, respectively) as well as results of an aberration correction of the parabolic mirror. Furthermore, we define a measure for the quality of our experimental achievements. From that, we envision absorption efficiencies beyond 80%.
