Laser frequency stabilization to a single ion
Ekkehard Peik, Tobias Schneider, Christian Tamm
A fundamental limit to the stability of a single-ion optical frequency standard is set by quantum noise in the measurement of the internal state of the ion. We discuss how the inte…

Frequency comparisons and absolute frequency measurements of 171Yb+ single-ion optical frequency standards
E. Peik, B. Lipphardt, H. Schnatz +3
We describe experiments with an optical frequency standard based on a laser cooled Yb ion confined in a radiofrequency Paul trap. The electric-quadrupole transition fro…
