Optical Pumping - an overview ScienceDirect Topics

The technique named “ optical pumping ” consists of absorbing pump light in order to excite erbium ions and provide population inversion in a given energy band. As seen in Figure 4.1, optical pumping may efficiently be performed around λ=0.98 μm from the fundamental ground state level 4 I 15/2 into the 4 I 11/2 level. Optical pumping may also be performed in the short-wavelength band of ...

Optical pumping physics Britannica

Optical pumping, in physics, the use of light energy to raise the atoms of a system from one energy level to another. A system may consist of atoms having a random orientation of their individual magnetic fields. When optically pumped, the atoms will undergo a realignment of individual magnetic fields with respect to the direction of the light beam; that is, there will be a rearrangement of ...

Optical pumping - Wikipedia

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 1966 Nobel Prize winner Alfred Kastler in the early 1950s.. Optical pumping is also used to cyclically ...
