Abstract

We perform laser spectroscopy of Yb+ ions on the 4f146s 2 S1/2-4f^135d6s^3 D[3/2]1/2 transition at 297 nm. The frequency measurements for 170Yb+, 172Yb+, 174Yb+, and 176Yb+ reveal the specific mass shift as well as the field shifts. In addition, we demonstrate laser cooling of Yb+ ions using this transition and show that light at 297 nm can be used as the second step in the photoionization of neutral Yb atoms.
