Ultra-stable transportable ultraviolet clock laser using cancellation between photo-thermal and photo-birefringence noise
Benjamin Kraus, Sofia Herbers, Constantin Nauk +3
Optical clocks require an ultra-stable laser to probe and precisely measure the frequency of the narrow-linewidth clock transition. We introduce a portable ultraviolet (UV) laser s…
A transportable clock laser system with an instability of
Sofia Herbers, Sebastian Häfner, Sören Dörscher +3
We present a transportable ultra-stable clock laser system based on a Fabry-Pérot cavity with crystalline AlGaAs/GaAs mirror coatings, fused silica (FS) mirror su…
A transportable optical lattice clock with uncertainty
S. B. Koller, J. Grotti, St. Vogt +5
We present a transportable optical clock (TOC) with Sr. Its complete characterization against a stationary lattice clock resulted in a systematic uncertainty of ${7.4 \times…
Realization of a time-scale with an accurate optical lattice clock
C. Grebing, A. Al-Masoudi, S. Dörscher +7
Optical clocks are not only powerful tools for prime fundamental research, but are also deemed for the re-definition of the SI base unit second as they now surpass the performance…
8E-17 fractional laser frequency instability with a long room-temperature cavity
Sebastian Häfner, Stephan Falke, Christian Grebing +5
We present a laser system based on a 48 cm long optical glass resonator. The large size requires a sophisticated thermal control and optimized mounting design. A self balancing mou…
Ultra-stable laser with average fractional frequency drift rate below
Christian Hagemann, Christian Grebing, Christian Lisdat +6
Cryogenic single-crystal optical cavities have the potential to provide highest dimensional stability. We have investigated the long-term performance of an ultra-stable laser syste…
