Phys. Rev. A 72, 023401 (2005) [13 pages]Relaxation of atomic polarization in paraffin-coated cesium vapor cellsReceived 31 March 2005; published 1 August 2005 The relaxation of atomic polarization in buffer-gas-free, paraffin-coated cesium vapor cells is studied using a variation on Franzen’s technique of “relaxation in the dark” [ Franzen Phys. Rev. 115 850 (1959)]. In the present experiment, narrow-band, circularly polarized pump light, resonant with the Cs D2 transition, orients atoms along a longitudinal magnetic field, and time-dependent optical rotation of linearly polarized probe light is measured to determine the relaxation rates of the atomic orientation of a particular hyperfine level. The change in relaxation rates during light-induced atomic desorption (LIAD) is studied. No significant change in the spin relaxation rate during LIAD is found beyond that expected from the faster rate of spin-exchange collisions due to the increase in Cs density. © 2005 The American Physical Society URL:
