Detection of nonresonant impurity gases in alkali vapor cells Academic Article uri icon


  • We show that even small amounts of impurity gases significantly change the properties of the nonlinear Faraday effect in alkali vapor cells. These changes result from velocity-changing collisions. We propose a simple method of detection and measurement of the impurities based on this effect. © 2002 American Institute of Physics.
