Hyperfine Polarization and Its Normal Gradient Coefficient of 87Rb Atoms in theVicinity ( 10 5 cm) of Coated and Uncoated Pyrex Glass Surfaces

چکیده
113003-1 We have made regionally specific measurement of the hyperfine polarization hS Ii of 87Rb atoms in the vicinity ( 10 5 cm) of coated and uncoated Pyrex glass surfaces. We find that the polarization near an uncoated surface decreases rapidly with decreasing distance from the surface whereas for a silicone-coated surface the polarization is independent of the distance from the surface. We have also determined the normal gradient coefficient S I of the hyperfine polarization in uncoated cells. In a representative uncoated cell, at a Rb density 7:35 1013 cm 3 and a pump beam intensity 1:3 W=cm2, we find S I 24 7 m 1.

We made regionally specific measurement of the hyperfine polarization kS ·Il of Rb atoms in the vicinity s,10−5 cmd of coated and uncoated Pyrex glass surfaces in optical pumping cells. This is in contrast to the previous hyperfine polarization studies, where the quantity measured is the bulk hyperfine polarization, which depends on surface interactions averaged over the entire cell surfaces.

متن کاملMapping surfaces using regionally specific hyperfine polarization
It is well known that coatings have a very dramatic effect in optical pumping experiments. For example, in a typical uncoated Pyrex glass cell, a single wall collision destroys the spin polarization of Rb atoms whereas it takes thousands of wall collisions to relax the spin polarization of Rb atoms on coated walls [1,2]. Similar dramatic effect of coatings is observed for nuclear spin polarized...

We present a detailed experimental and theoretical study of edge enhancement in optically pumped Rb vapor in coated cylindrical pyrex glass cells. The Zeeman polarization of Rb atoms is produced and probed in the vicinity (∼10−4 cm) of the cell surface by evanescent pump and probe beams. Spin-polarized Rb atoms diffuse throughout the cell in the presence of magnetic field gradients. In the pres...

In an evanescent wave magnetometer the Zeeman polarization is probed at micrometer to submicrometer distances from the cell surface. The electron paramagnetic resonance lines of an evanescent wave magnetometer in the presence of a magnetic field gradient exhibit edge enhancement seen previously in nuclear magnetic resonance lines. We present a theoretical model that describes quantitatively the...
متن کاملMethod for measuring the dwell time of spin-polarized Rb atoms on coated pyrex glass surfaces using light shift.
We present a simple method for directly measuring the average dwell time of spin-polarized Rb atoms on coated Pyrex glass surfaces. The method relies on the light shift of the Zeeman resonances of spin-polarized Rb atoms pumped and probed by evanescent waves, and does not depend on the microscopic details of surface interactions. We use a cell whose length is adjustable between 70 and 500 micro...
