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…
Analysis of thermal radiation in ion traps for optical frequency standards
Miroslav Doležal, Petr Balling, Peter B R Nisbet-Jones +16
In many of the high-precision optical frequency standards with trapped atoms or ions that are under development to date, the AC Stark shift induced by thermal radiation leads to a…
Astrodynamical Space Test of Relativity using Optical Devices I (ASTROD I) - A class-M fundamental physics mission proposal for Cosmic Vision 2015-2025
Thierry Appourchaux, Raymond Burston, Yanbei Chen +33
ASTROD I is a planned interplanetary space mission with multiple goals. The primary aims are: to test General Relativity with an improvement in sensitivity of over 3 orders of magn…
Quantum Physics Exploring Gravity in the Outer Solar System: The Sagas Project
P. Wolf, Ch. J. Bordé, A. Clairon +52
We summarise the scientific and technological aspects of the SAGAS (Search for Anomalous Gravitation using Atomic Sensors) project, submitted to ESA in June 2007 in response to the…
Optical Clocks in Space
S. Schiller, A. Goerlitz, A. Nevsky +18
The performance of optical clocks has strongly progressed in recent years, and accuracies and instabilities of 1 part in 10^18 are expected in the near future. The operation of opt…
