WebOptical pumping is a process used in high frequency spectroscopy which was developed by A. Kastler. It allows the spectroscopy of atomic energy states in an energy region which is not accessible by means of direct, optical observation. Kastler was awarded the Nobel Prize for Physics for this in 1966. WebApr 29, 2024 · Optical pumping is a process to redistribute the populations P F,M of Zeeman sublevels F, M within hyperfine components, defined as a light-induced process that changes the optical properties of an atomic medium. It is an important method to get the atoms prepared in definite quantum states and plays a key role in atomic magnetometers. hidden secrets game for pc free download
