Laser cooling and spectroscopy of trapped Yb+ ions at 297nm — •Hendrik-Marten Meyer, Matthias Steiner, and Michael Köhl — Department of Physics, University of Cambridge, Cavendish Laboratory, JJ Thomson Avenue, CB3 0HE, Cambridge, United Kingdom
In the last decade trapped Yb+ ions have been used in quantum information processing, precision measurements and hybrid systems. We explore the 2S1/2 - 3D[3/2]1/2 transition at 297 nm in Yb+ and provide absolute frequency measurements of this transition for even Yb+ isotopes. Light at 297 nm is generated using sum frequency generation of light near 532 nm and 672 nm. We also show that this light can be used for laser cooling of trapped Yb+ ions. The possibility to address the 2S1/2 - 3D[3/2]1/2 transition makes a new lambda-system available in Yb+ which opens new ways of quantum state manipulation of these ions.
