摘要：

We describe a cesium atomic beam (10(14) atoms s-1, 6 X 10(16) atoms sr-1 s-1) spin polarized using light from two diode lasers. Of the atoms, 95% may be placed into either the 6S1/2(F,m(F)) = (3,3) or (4,4) state, with less than 2 X 10(-4) of the atoms left in the depleted hyperfine level. The latter fraction rises linearly with atomic beam intensity because of reabsorption of light scattered during the optical pumping process. This and other effects limiting complete hyperfine pumping are discussed.
