Abstract

Optical pumping of helium, using the 2³S–2³P line at 1.083 μm, can be performed with a tunable neodymium laser [La_1−xNd_xM_gAl₁₁O₁₉ (LNA)]. The LNA crystal, longitudinally excited by an Ar⁺ gas laser, delivers a usable power of about 300 mW. A ³He cell at 0.3 Torr can thus nuclearly polarized up to 60%. Preliminary results are also obtained with a LNA laser pumped by discharge lamps.
