Define Optical Pumping at Melissa Eide blog

Define Optical Pumping. Optical pumping (happer 1972) is one of the earliest examples wherein optical radiation qualitatively modifies the properties. Optical pumping is a sophisticated technique employed in physics and various scientific fields to manipulate the energy levels. Optical pumping, in physics, the use of light energy to raise the atoms of a system from one energy level to another. Optical pumping uses either cw or pulsed light emitted by a powerful lamp or a laser beam. These internal degrees of freedom are angular momentum states of the atomic ground. The process of raising large number of atoms from lower energy to a higher energy level is called pumping. Optical pumping can be realized by light from powerful incoherent sources. Optical pumping uses light to affect the internal degrees of freedom of a sample of atoms in a vapor.
