Optical Pumping - an overview | ScienceDirect Topics

Optical pumping was first developed, in terms of theory, in 1950 by A. Kastler, and actually realized for experimentation in 1960 by T.H. Maiman. Initially, a pulse discharge lamp was used to obtain an intense flash of light in a broad spectrum (white and UV light). The process is repetitive with a frequency of a few Hz to a few tens of Hz.

An optical pumping magnetometer takes advantage of the differences between electron energy levels in an atom of alkali metal vapor. The energy of an electron can assume one of several levels, depending on the orbit the electron follows and the orientation of the magnetic moment of the electron with respect to the ambient magnetic field (parallel or antiparallel).
