Abstract

We have made a systematic study of rubidium optical pumping in a simple cylindrical cell geometry with a high-power 10 W diode laser array, low magnetic fields, and buffer-gas pressures of less than 50 torr. We have determined rubidium polarizations experimentally for H2, N2, He, and Ar buffer gases, with Rb number densities from 1012 to 1013 cm-3. Comparison to a relatively simple optical pumping model allows us to extract useful information about radiation trapping and quenching effects.
