Optical pumping cesium beam tubes

WebA more symmetric beam reversal is possible with optical pumping methods, since all atoms may be included regardless of velocity and position within the beam. This should permit a better cancellation of cavity phase shifts. Angle tuning of the laser may result in velocity selection of atoms in the cesium beam, favoring slower velocity atoms, which http://files.aws.org/conferences/abstracts/2006/012.pdf
