Resonant photo-ionization of Yb+ to Yb2+

Simon Heugel, Martin Fischer, Vladimir Elman +3

We demonstrate the controlled creation of a ${}^{174}\mathrm{Y}{\mathrm{b}}^{2+}$ ion by photo-ionizing ${}^{174}\mathrm{Y}{\mathrm{b}}^{+}$ with weak continuous-wave lasers at ultraviolet wavelengths. The ph…
