A Synchronous Spin-Exchange Optically Pumped NMR-Gyroscope

WebSpin-exchange pumped NMR gyroscopes [1,2,3,4,5,6] use the precession of spin-polarized nuclei to measure rotation.A vapor cell contains one or more isotopes of noble gas atoms and an alkali-metal vapor. The alkali-metal vapor is optically pumped using circularly polarized near-infrared laser light. Optical pumping is a process in which light is used to raise (or "pump") electrons from a lower energy level in an atom or molecule to a higher one. It is commonly used in laser construction to pump the active laser medium so as to achieve population inversion. The technique was developed by the 1966 Nobel Prize winner Alfred Kastler in the early 1950s. brickwork reinforcement mesh https://mcseventpro.com
