Optical Clock

An optical atomic clock employs a clock transition in the optical or visual regime, typically between 400 and 1000 nm wavelength. Such electromagnetic oscillations are multi-THz, in contrast to the present standard cesium clocks that are based on a hyperfine transition at 9192631770 Hz. Because of the much higher oscillatory frequency, nowadays optical clocks are outrunning the accuracy of cesium clocks by several orders of magnitude.
