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

Optical pumping, the inversion technique used in the original ruby laser, is an extension of the “three-level” maser scheme proposed by Bloembergen (Bloembergen, 1956) for microwave solid-state masers.In Figure 2.6 we show a system of three energy levels, whose occupation, as shown by the length of the bars, obeys the Boltzmann distribution.

2021-9-17 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 ...
