A high-stability optical clock based on a continuously ground-state cooled Al ion without compromising its accuracy
Fabian Dawel, Lennart Pelzer, Kai Dietze +12
Single ion optical clocks have shown systematic frequency uncertainties below , but typically require more than one week of averaging to achieve a corresponding statistic…

Coherent photo-thermal noise cancellation in a dual-wavelength optical cavity for narrow-linewidth laser frequency stabilisation
Fabian Dawel, Alexander Wilzewski, Sofia Herbers +7
Optical resonators are used for the realisation of ultra-stable frequency lasers. The use of high reflectivity multi-band coatings allows the frequency locking of several lasers of…
