Optical pumping and relaxation in the cells with antirelaxation coating


The cells with antirelaxation coating of the walls are widely used in modern magnetometry. That is why the optical pumping and relaxation processes in such cells are actively investigated in the laboratory. The most interesting researches and results in the area:


  • Research of the kinetics of the very interesting phenomenon of the Light Induced Atomic Desorption from paraffin coating for alkaline atoms.

  • Detailed investigation of the relaxation processes in coated cells revealed some unknown “extra” wall relaxation which was observed when the concentration of alkaline atoms was increased by heating the cell and was absent when the same was increased by LIAD.

  • The new theory of the laser optical pumping in coated cells was elaborated. The theory exactly describes the maxwelization by wall collisions of the initial laser light induced monokinetic velocity distribution of the atomic polarization moments and is capable to achieve the considerable agreement with the experimental value of the saturating light power of the rotation angle of the light polarization plane whereas the usual theory predicts the value by two orders of magnitude less than the experimental one.
