Full solid angle imaging of a single ion — •Martin Fischer1,2, Robert Maiwald1,2, Andrea Golla1,2, Marianne Bader1,2, Markus Sondermann1,2, and Gerd Leuchs1,2 — 1Max Planck Institute for the Science of Light, Erlangen, Germany — 2Institute of Optics, Information and Photonics, University of Erlangen-Nuremberg, Erlangen, Germany
In most ion trapping experiments the geometry of the trap as well as application specific restrictions significantly reduce the solid angle under which the ion can be observed. In our setup we make use of an ion trap designed to minimize the obscured solid angle [1]. This trap is combined with a parabolic mirror covering 81 % of the solid angle providing us with a setup capable of imaging our single emitter with sub-wavelength resolution [2]. We report on the highest resolution in imaging a single atomic emitter. Furthermore our system shows high sensitivity to misalignment of the ion from the focus of the parabolic mirror making sub-wavelength displacements easily detectable.
