Thermal noise and mechanical loss of SiO/TaO optical coatings at cryogenic temperatures
John M Robinson, Eric Oelker, William R Milner +8
Mechanical loss of dielectric mirror coatings sets fundamental limits for both gravitational wave detectors and cavity-stabilized optical local oscillators for atomic clocks. Two a…
Simple and compact diode laser system stabilized to Doppler-broadened iodine-lines at 633 nm
Florian Krause, Erik Benkler, Christian Nölleke +2
We present a compact iodine-stabilized laser system at 633 nm, based on a distributed-feedback laser diode. Within a footprint of cm the system provides 5 mW of f…
Optical frequency ratio of a single-ion clock and a lattice clock
Sören Dörscher, Nils Huntemann, Roman Schwarz +6
We report direct measurements of the frequency ratio of the 642 THz -- electric octupole transition in and the 429 THz…
Long term measurement of the Sr clock frequency at the limit of primary Cs clocks
R. Schwarz, S. Dörscher, A. Al-Masoudi +7
We report on a series of 42 measurements of the transition frequency of the 429~THz (5s)~S--(5s5p)~P line in Sr taken over three years from 2017 to 2019.…
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…
