Abstract: Optical pumping of an optically thick atomic vapor typically requires aquenching buffer gas, such as N$ {2}$, to prevent radiation trapping ofunpolarized photons which would depolarize the atoms. We show that opticalpumping of a trace contamination of Rb present in K metal results in a 4.5times higher polarization of K than direct optical pumping of K in the absenceof N$ {2}$. Such spin-exchange polarization transfer from optically-thinspecies is useful in a variety of areas, including spin-polarized nuclearscattering targets and electron beams, quantum-non-demolition spinmeasurements, and ultra-sensitive magnetometry.
