Magneto-optical trapping of Zinc — •Lukas Möller, Felix Waldherr, and Simon Stellmer — Universität Bonn, Germany

Laser-cooling and trapping of neutral atoms is a widely used technique in contemporary atomic physics. The element zinc, an alkaline-earth-like metal, is a promising candidate for a new optical clock. Work on zinc also motivates the development of new cw-laser sources in the UV range, since its strong cooling transition lies at 213.9 nm. We report magneto-optical trapping of all 5 stable isotopes of Zinc, as the first step towards spectroscopy of the clock transition.
