An ion trap design for a space-deployable strontium-ion optical clock
Alessio Spampinato, Jonathan Stacey, Sean Mulholland +5
Optical atomic clocks demonstrate a better stability and lower systematic uncertainty than the highest performance microwave atomic clocks. However, the best performing optical clo…
Guidelines for developing optical clocks with fractional frequency uncertainty
Moustafa Abdel-Hafiz, Piotr Ablewski, Ali Al-Masoudi +42
There has been tremendous progress in the performance of optical frequency standards since the first proposals to carry out precision spectroscopy on trapped, single ions in the 19…
Compact laser system for a laser-cooled ytterbium ion microwave frequency standard
S. Mulholland, H. A. Klein, G. P. Barwood +6
The development of a transportable microwave frequency standard based on the ground-state transition of at ~12.6 GHz requires a compact laser system for coo…
Laser-cooled ytterbium ion frequency standard
S. Mulholland, H. A. Klein, G. P. Barwood +6
We report on the development of a trapped-ion, microwave frequency standard based on the 12.6 GHz hyperfine transition in laser-cooled ytterbium-171 ions. The entire system fits in…
Development of a strontium optical lattice clock for the SOC mission on the ISS
S. Origlia, S. Schiller, M. S. Pramod +25
The ESA mission "Space Optical Clock" project aims at operating an optical lattice clock on the ISS in approximately 2023. The scientific goals of the mission are to perform tests…
Development of a strontium optical lattice clock for the SOC mission on the ISS
K. Bongs, Y. Singh, L. Smith +24
Ultra-precise optical clocks in space will allow new studies in fundamental physics and astronomy. Within an European Space Agency (ESA) program, the Space Optical Clocks (SOC) pro…
Robust frequency stabilization of multiple spectroscopy lasers with large and tunable offset frequencies
Alexander Nevsky, Soroosh Alighanbari, Qun-Feng Chen +7
We demonstrate a compact and robust device for simultaneous absolute frequency stabilization of three diode lasers whose carrier frequencies can be chosen freely relative to the re…
The Space Optical Clocks Project: Development of high-performance transportable and breadboard optical clocks and advanced subsystems
S. Schiller, A. Görlitz, A. Nevsky +28
The use of ultra-precise optical clocks in space ("master clocks") will allow for a range of new applications in the fields of fundamental physics (tests of Einstein's theory of Ge…
