TOPTICA’s frequency comb DFC CORE+ demonstrates world record stability, as reported in an article by scientists of the Physikalisch-Technische Bundesanstalt (PTB) Braunschweig, Germany and TOPTICA.

TOPTICA’s frequency comb DFC CORE+ demonstrates world record stability, as reported in an article by scientists of the Physikalisch-Technische Bundesanstalt (PTB) Braunschweig, Germany and TOPTICA.

This paves the way for a future improvement of some of the most sensitive instruments ever created: optical clocks and gravitational wave detectors. Both benefit from transferring the ultimate stability to a specific wavelength.
