Study of a Nuclear Magnetic Resonance (NMR) Gyro Using Optically Pumped Helium Isotopes.

摘要

In this experimental investigation the polarization levels and relaxation rates for optically pumped 4He and 3He isotopes were determined. An experiment verified that simultaneous magnetic resonance of both isotopes in a common volume may be attained. Characteristics of some experimental semiconductor diode lasers were measured with a view toward replacing helium lamps as an optical pumping radiation source with diode lasers. A semiconductor diode laser was successfully used to monitor polarized 4He atoms. (Author)
