Paper Abstract

Calculations are presented on continuous plasma generation by the optical pumping of a supersonic lithium beam. The plasma density is computed as a function of pump intensity on the Li(2s-2p) and Li(2p-3d) transitions. The factors affecting Li- generation are considered.. It is found that modest optical pump powers allow the generation of Li currents at up to 10 mA cm-2, at approximately unity ratio of electrons to Li- ions.
