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 1, 2024 · It will be shown that the region to study optical pumping effects corresponds to the transitions that originate in the lower hyperfine state of the ground state manifold ( ). Therefore, we begin this section with a detailed discussion of what we will refer to as a sublevel pumping calculation.

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 4, 2010 · Optical pumping is a process that stochastically increases the energy levels of atoms in a magnetic eld to their highest Zeeman energy state. This technique is important for its applications in applied atomic and molecular physics, particularly in the construction of lasers.
