Abstract

Spectroscopy of ions in electromagnetic traps using laser-cooling and detection has reached a sensitivity where it is now possible to unambiguously monitor state changes in a single ion. While these techniques may not be generally applicable, the sensitivity and precision that is obtained for laser-cooled ions give broad opportunities for experiments in many areas of fundamental physics and-high resolution spectroscopy. In this paper, the authors describe two experiments with a single laser-cooled Hg+ ion. In one they achieve the highest fractional resolution (highest Q) in atomic or molecular spectroscopy, and in the second they cool the ion to its zero-point energy.
