Frequency stability of cryogenic silicon cavities with semiconductor crystalline coatings
Dhruv Kedar, Jialiang Yu, Eric Oelker +7
State-of-the-art optical oscillators employing cryogenic reference cavities are limited in performance by the Brownian thermal noise associated with the mechanical dissipation of t…
Excess noise and photo-induced effects in highly reflective crystalline mirror coatings
Jialiang Yu, Dhruv Kedar, Sebastian Häfner +9
Thermodynamically induced length fluctuations of high-reflectivity mirror coatings put a fundamental limit on sensitivity and stability of precision optical interferometers like gr…
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…
Ultimate stability of active optical frequency standards
Georgy A. Kazakov, Swadheen Dubey, Anna Bychek +3
Active optical frequency standards provide interesting alternatives to their passive counterparts. Particularly, such a clock alone continuously generates highly-stable narrow-line…
