Optical atomic clocks
WebMay 17, 2024 · Optical atomic clocks, running at higher frequencies, offer greater precision because they divide time into smaller units and have a high "quality factor," which reflects how long the atoms can tick on their own, without outside help. Optical clocks are expected to be the basis for a future redefinition of the second. WebDec 16, 2024 · A typical atomic clock does this by first using a system of lasers to corral a gas of ultracooled atoms into a trap formed by a laser. A second, very stable laser, with a …
