Developments in Synchronous Spin-Exchange Optically Pumped NMR Gyroscopes
ORAL
Abstract
In this study, we present a spin-exchange pumped NMR comagnetometer with 131Xe, 129 Xe, and Rb atoms that is continuously polarized transverse to a pulsed bias field. Previously, we showed that both Xe species can be simultaneously excited using Rb polarization modulation (PM) or bias pulse repetition rate modulation (PDM). Here, we present developments in our modulation scheme, using a hybrid PM-PDM modulation which is combination of two modulations introduced before. This scheme achieves µHz-scale rotation sensitivity and suppresses sub-Hz magnetic field fluctuations by a factor of 1500. We will describe systematic error studies with this system.
