Today’s best optical clocks achieve an amazing accuracy and would be off by less than one second over the age of the universe. These clocks rely on probing optical transitions in cold atoms with very stable and narrow linewidth laser light. The probed atoms provide the long-term stability and accuracy of the clock. Frequency combs allow to combine the most stable lasers with the best reference atoms. This requires a stability transfer from the wavelength of the best available lasers to the wavelength of the cold atom transition in use.
