The research has also led to the construction of extremely precise clocks that could become the future basis for a new standard of time, with more than hundred-fold greater precision than present-day caesium clocks, it said.
Now, these previous competitors can complement one another, and the technology of the optical clock leads to a considerable improvement of the established caesium clocks.
Caesium fountains are more accurate than "normal" atomic caesium clocks, because in fountains, the caesium atoms are cooled down with the aid of laser beams and come ever slower.
