Erratum: Light-induced desorption of alkali-metal atoms from paraffin coating [Phys. Rev. A 66 , 042903 (2002)]

Abstract

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 greater than or similar to 1 s), 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.
