Multi-ion frequency reference using dynamical decoupling
Lennart Pelzer, Kai Dietze, Víctor J. Martínez-Lahuerta +6
We present the experimental realization of a continuous dynamical decoupling scheme which suppresses leading frequency shifts in a multi-ion frequency reference based on $^{40}\mat…

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…
