Optical atomic clocks
WebNov 19, 2024 · Optical atomic clocks are our most precise tools to measure time and frequency. They enable precision frequency comparisons between atoms in separate locations to probe the space-time variation of fundamental constants, the properties of dark matter, and for geodesy. Webatoms/ions when realizing a compact optical atomic clock. All of the relevant transition wavelengths for cooling and trapping lie in the visible or near-infrared and can be eas-ily reached with semiconductor devices (see Fig. 1). Fur-ther reduction of the complexity of the setup comes from the use of a magnetic-field-induced spectroscopy scheme to
