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.

A Synchronous Spin-Exchange Optically Pumped NMR-Gyroscope

WebAtomic magnetometers (AMs), optically pumped magnetometers (OPMs), or optical quantum sensors (OQSs) find many applications in science and the industry. Perhaps the … WebJun 19, 2024 · The ability to orient atomic spins via optical pumping has important implications for the fields of quantum information and metrology, and while polarization … high compression foam engineering

Optically Pumped Magnetometers for Biomagnetic Measurements

WebFig. 1 Light from a circularly polarized laser beam optically pumps the Rb atoms, while light from a second laser beam probes the magnetic field-dependent spin orientation through polarization rotation. Both the transmission and polarimeter signal show a resonance as a function of magnetic field Optically-Pumped Magnetometers for MEG 995 WebApr 11, 2024 · We perform a new scheme of magnetic state selection in optically detected compact cesium beam clocks. Unlike the conventional method, we select atoms in the ground state F = 4, m F ≠ −4 by pointing the atomic collimator to the convex pole of the magnet realizing the two-wire magnetic field and detect atoms in F = 3 after interacting … WebMay 20, 2024 · Thus at a conceptual level, an optically pumped magnetometer can be visualized as a collection of isolated atoms interacting with a common laser beam. What makes atomic magnetometers remarkable is that a practical implementation of such device is not very different from the idealized picture. high compression ford model t
