Optical atomic clock review
WebModern clocks such as atomic fountains or optical lattices that use sequential interrogation are found to generate type of noise that mimics and adds to the instability inherent in atom or ion counting. ... Analysis of the effect and its consequence as applied to optical standards has been treated in a major review (Ludlow, et al., 2015) that ... Web2.2 Operational principle of optical atomic clocks. Modern optical atomic clocks are today the most accurate frequency standards [209, 267].Their underlying principle of operation is based on the fact that the energy corresponding to an atomic transition is the same for all identical atoms and remains constant (independent of space and time).

WebJun 10, 2024 · These include the atomic clocks that provide U.S. official time or the signals from GPS satellites, by comparing their output to reference combs with frequencies 1,000 or more times higher. And it makes possible optical clocks with “tick” rates about 100,000 times faster than microwave models. Key Papers WebMar 5, 2024 · This issue would seem to present a dilemma: Adding atoms to the optical lattice provides a larger ensemble and therefore a higher precision measurement. But it also exacerbates the role of atom-atom interactions, which modify the clock-transition frequency in direct proportion to the atomic density [ 8, 9 ].
