Optical pumping of Rubidium High Energy Physics

Optical Pumping of Rubidium Advanced Laboratory, Physics 407 University of Wisconsin Madison, WI 53706 Abstract A Rubidium high-frequency lamp is used as the pumping light source to excite Rubidium atoms in a sample cell. The pumping source light is filtered to transmit the D1 Rb line and polarizers are used to produce circular polarization.

Optical Pumping of Rubidium Vapor

2.1. Optical Pumping of Rubidium Vapor We investigated the radio-frequency transitions in Rb87 and Rb85. Rubidium is an alkali metal atom that has a 2S 1/2 ground state and 2 P 1/2 and 2 3/2 excited states (Figure 1). The optical transitions between the ground state and the two excited states are the origin of the D 1 f=2 f=1 f=2 f=1 5P 5S P P

Rb: Optical Pumping in Rubidium

Oct 19, 2018· Rb: Optical Pumping in Rubidium. Circularly polarized light from a Rubidium lamp is used to "pump" Rb vapour into a specific m F level. Isotopic abundance ratios and the g-factor for each level may be calculated. Alfred Kastler won the Nobel Prize in 1966 for the development of optical pumping. Optical pumping was key step in the development of

In this prac you will study the “optical pumping” of rubidium (Rb) atoms. Optical pumping produces a non-equilibrium distribution of energy states in a collection of atoms. This is done by shining resonant radiation (of optical or near-optical frequencies) at the ensemble. Another way of manipulating energy states is by the use of RF (radio
