Short Description
Optical atomic clock, based on a single Ytterbium 1+ ion, trapped in an ion trap. The device contains a 781 nm "clock laser" which is stabilized to a high-finesse optical cavity for short-term stability. Long-term stability is obtained by continuous scanning and laser spectroscopy of the Yb1+ ion. The optical reference signal is extracted from the device via a Doppler-compensated fiber and used to stabilize a frequency comb system.
