Abstract :
A report is presented on experiments to understand the laser optical pumping efficiency for the Optically Pumped Polarized Ion Source (OPPIS) at LAMPF. Measurements were made of ion beam polarization and current vs. laser power and potassium vapor thickness in order to understand the dependence of source performance on laser power and other parameters. Attempts to fit the data with simple scaling models to evaluate projected performance improvements are shown. The development of economical ways to make more efficient use of available laser power is described.<>
