Phys. Rev. A 66, 042903 (2002) [12 pages]Light-induced desorption of alkali-metal atoms from paraffin coatingSee Also: Erratum Received 9 July 2002; published 23 October 2002 Observation of nonthermal, light-induced desorption of Cs and Rb atoms from paraffin coating is reported. Buffer-gas-free paraffin-coated cells containing Cs and Rb were exposed to laser light of various intensities and frequencies, and the change of the vapor densities as a function of time was investigated. Because atomic polarization relaxes very slowly in paraffin-coated cells (spin-relaxation times can be ≳1s), they are applied in a variety of precision measurements (e.g., magnetometry, discrete symmetry tests, etc.). Light-induced desorption may be useful in such measurements as a method to control atomic density without changing the temperature of the cell. © 2002 The American Physical Society URL:
