Abstract

A color‐center laser operating at 1.08 μm has been used to optically pump a thermal He(2³S) atom beam via 2³S→2³P transitions. Even modest laser powers (∼10 mW) result in more efficient optical pumping than is obtained using a 400‐W rf‐excited helium resonance lamp. The laser also permits optical pumping via transitions to selected 2³P fine structure levels.
