We present measurements of the circular dichroism of optically pumped Rb vapor near the D-1 resonance line. Collisions with the buffer gases He-3 and N-2 reduce the transparency of the vapor, even when fully polarized. We use two methods to measure this effect, show that the He results can be understood from RbHe potential curves, and show how this effect conspires with the spectral profile of the optical pumping light to increase the laser power demands for optical pumping of very optically thick samples.
