| Zusammenfassung | We present recent results on the 688 THz Yb+ single laser-cooled ion optical frequency standard. The total relative uncertainty of the absolute frequency measurement of the standard was reduced to 2.0E-15. Plans to observe the elec-tric-octupole transition of Yb+ at 642 THz with sub-hertz resolution are dis-cussed. Measurements of the frequency ratio between the 688 THz and 642 THz Yb+ frequency standards will permit to search for temporal variations of the fine structure constant. |
