In the research community, optical clocks have been attracting increasing...
Researchers from the Physikalisch-Technische Bundesanstalt (PTB) have thoroughly analyzed the noise processes in their optical lattice clock with neutral strontium atoms. This analysis proves that their optical atomic clock has reached the best stability worldwide thanks to a newly developed laser system whose frequency is extremely stable. This allows high-precision measurements in a short time and considerably facilitates the future reduction of the total measurement uncertainty down to a few parts in 1E18.
