Precision Fibre and Free Space Transfer
- Robert Scholten (The University of Melbourne)
Networks of optical clocks find applications in precise navigation, in efforts to redefine the fundamental unit of the ‘second’ and in gravitational tests. As the frequency uncertainty and instability for state-of-the-art optical clocks has reached the 10^−19 level, the vision of a global-scale optical network that achieves comparable performances requires the dissemination of time and...
REFIMEVE is a national metrological network for time and frequency dissemination using the academic fiber network. It enables the coherent dissemination of time and/or frequency reference signals from LNE-SYRTE to around 15 labs and more than 30 in the future. We will show the latest extensions of the network in the Paris urban area and all over France, the architecture required for such a...
Frequency comparison using ultra-stable, free-space laser links between transportable optical atomic clocks will result in globally significant advancements in applications spanning from fundamental physics, to outputs with immediate societal impact. Here, we report on our work to demonstrate a low size, weight, and power, continuous-wave laser technology that is capable of free-space...
