Description

We present the results of progress in optical pumping for the Optically Pumped Polarized Ion Source (OPPIS) at LAMPF. Several methods of estimating vapor polarization are discussed, including details of several techniques for measuring optical rotation. The polarization of Na vapor pumped with two single frequency ring lasers as a function of laser beam size, frequency, and power is examined and optimized. Data is presented on the polarization preserving properties of a spontaneously formed wall coating and Dryfilm and their destruction. An electro-optic modulator (EOM) is used to increase the spectral coverage of the Na absorption profile and hence improve optical pumping efficiency. We assess the advantages of using a titanium:sapphire (TiSaf) laser with power exceeding 3 W at 770 nm to pump K for a polarized vapor target in OPPIS. (author)
