Description
We report on measurements of the polarization for 3He using optically pumped potassium vapor. We achieve a 3He polarization greater than 40% in a mid-sized double-chamber glass target cell filled with 3He gas using a single Ti:sapphire laser. Applied to the production of polarized 3He as an atomic beam source for colliders, these developments could have significant impact on future studies of neutron spin structure. The results also motivate the development of high power diode lasers tuned to the appropriate potassium wavelengths
