Optical Pumping of Rubidium Vapor | Experiments

Optical Pumping experiment equipment. Rubidium vapor in a weak (~.01-10 gauss) magnetic field controlled with Helmholtz coils is pumped with circularly polarized D1 light from a rubidium rf discharge lamp. The degree of magnetization of the vapor is inferred from a differential measurement of its opacity to the pumping radiation

Optical Pumping : Experiment and Theory Revisited

Optical Pumping : Experiment and Theory Revisited

The objective of this paper is to share our enthusiasm for optical pumping experiments and to encourage their use in researches on practical physics. The experimental technique has been well developed and the apparatus sophisticated, but, by paying attention to a few details, reliable operation can be repeated. Some theoretical principles for optical pumping are also introduced and they can

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. We now apply a “pump” or intense optical

Optical pumping uses light to affect the internal degrees of freedom of asample of atoms in a vapor. These internal degrees of freedom are angularmomentum states of the atomic ground state, which are populated whenlight is absorbed and emitted. This experiment reveals many phenomena ofquantum mechanics including angular momentum selection rules, the densitymatrix, and resonance
