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…

A transportable interrogation laser system with an instability of
Sebastian Häfner, Sofia Herbers, Stefan Vogt +2
We present an interrogation laser system for a transportable strontium lattice clock operating at 698 nm, which is based on an ultra-low-expansion glass reference cavity. Transport…

A high-performance optical lattice clock based on bosonic atoms
Stefano Origlia, Mysore Srinivas Pramod, Stephan Schiller +9
Optical lattice clocks with uncertainty and instability in the -range and below have so far been demonstrated exclusively using fermions. Here, we demonstrate a bosonic o…
