Principles of Operation of the Rubidium Vapor
2017-7-28 rubidium magnetometers described here normally employ a fairly high pressure buffer gas (3 cm Hg or higher) of neon and a filter is needed to pass the reso-nance radiation at X 7948 and reject X 7800. An inter-ference filter has been developed for this purpose* which transmits approximately 80% of the X 7948 radiation

Optical Pumping of Rubidium - UW–Madison
2019-2-11 The irradiating, circularly-polarized light effects a polarization of the atomic vapour in the absorption cell. This can be interpreted as follows: during the process of absorption, the polarized light transmits angular momentum to the rubidium atoms. The rubidium vapour is polarized and thus magnetized macroscopically.

Vector Magnetometer Using Rb Vapor - Physics
2011-10-25 (EIT) in rubidium vapor. In rubidium atoms, the Zeeman effect causes atomic states to shift when an external magnetic field is applied. The magnitude of these shifts, and consequently the strength of the magnetic field, can be mea-sured by recording electromagnetically induced transparency resonances with tuned laser fields.

Rubidium atom distribution and non-spectral
1998-7-6 The interference is believed to be caused by trapping of Rb atoms on condensed Ga particles residing in the vapour phase in the vicinity of the tube ends. In the presence of end caps the area close to the tube ends (where the atoms are residing) will become much hotter 40 , 41 which eliminates or reduces the formation of condensed Ga and hence ...
