Optical atomic clock review
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).
