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. WebApr 5, 2010 · Optically Pumped Atoms 1st Edition.

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. WebDec 11, 2024 · In an optically pumped alkali vapor cell with a high density of atoms, the attenuation of the pump light generates a spatially non-uniform distribution of the electronic spin polarization of alkali atoms, which is detrimental to biomagnetism applications of magnetometers as well as the hyperpolarization of noble gas atoms.
