Suppression of Spin-Exchange Relaxation Using Pulsed Parametric Resonance
ORAL
Abstract
A new method of optical pumping is presented in which $^{87}$Rb atoms are fully polarized perpendicular to a large DC magnetic field by applying a transverse AC coupled pulsed field. When the repetition rate of the pulsed field matches the Larmor frequency of the DC field, decoherence due to spin exchange collisions is suppressed beyond the light narrowed regime. We will present results demonstrating this further suppression and show the improved magnetometer response over a traditional light-narrowed parametric resonance magnetometer. This work is funded by the NSF.
