“…Because radiation damping is observed for large magnetizations, it is not surprising that we observed this effect at low fields in our LP 3 He samples. In fact, optically pumped 3 He Zeeman masers rely on radiation damping to sustain an active oscillation, as was first demonstrated at 32 G (24). A related device we have developed is a cohabitating, two-species 3 He/ 129 Xe Zeeman maser operating at fields ϳ1-3 G (25).…”

“…The first demonstration of the potential of hyperpolarized 3 He for precision measurements was in a maser configuration, by Robinson and Myint (1964), who reported a statistical uncertainty of

500 nHz / \sqrt{Hz}

using a lamp-pumped MEOP setup. This experiment also pioneered the use of a dual cell system, with the MEOP process occurring in one bulb, connected by a few mm diameter tube to the spherical maser chamber.…”

This article reviews the physics and technology of producing large quantities of highly spin-polarized 3He nuclei using spin-exchange (SEOP) and metastability-exchange (MEOP) optical pumping. Both technical developments and deeper understanding of the physical processes involved have led to substantial improvements in the capabilities of both methods. For SEOP, the use of spectrally narrowed lasers and K-Rb mixtures has substantially increased the achievable polarization and polarizing rate. For MEOP nearly lossless compression allows for rapid production of polarized 3He and operation in high magnetic fields has likewise significantly increased the pressure at which this method can be performed, and revealed new phenomena. Both methods have benefitted from development of storage methods that allow for spin-relaxation times of hundreds of hours, and specialized precision methods for polarimetry. SEOP and MEOP are now widely applied for spin-polarized targets, neutron spin filters, magnetic resonance imaging, and precision measurements.
