Circularly polarized light propagating at an angle to the external magnetic field does not optically pump atoms to full transparency under conditions common to spin-exchange optical pumping experiments. This causes excess absorption of the pumping light that can significantly reduce the efficiency of the optical pumping process even for angles of a few degrees.
