In this work, a rubidium fountain clock through an 84km commercial optical fiber link was used to steer the atomic time scale generated by a clock ensemble with 2 hydrogen masers and 8 high ...

Researchers at the Niels Bohr Institute, University of Copenhagen, have developed a tunable system that paves the way for ...

We report on the development of a long-term laser diode aging test bench that measures the spectral behavior of laser diodes over several years, in view of their applications in space Rb atomic clocks ...
