Abstract :
Recently the optical lattice clocks (OLCs) based on neutral atoms are leading the progress of clock research [1, 2]. As the optical lattice clock has a prominent short-term stability compared to the microwave clock and the ion clock intrinsically, it can contribute greatly to many fields such as precision measurement, fundamental science, astronomy, future industry, re-definition of the Second, and everywhere needs detection of extremely small changes of some physical quantities.
