Continuous Sub-Doppler-Cooled Atomic Beam Interferometer for Inertial Sensing
TLDR
In this paper , an inertially sensitive matter-wave interferometer in a three-dimensionalally-cooled atomic beam that mitigates decoherence while operating continuously is presented.Abstract:
In atomic sensors, continuous interrogation of laser-cooled atoms carries the benefits of improved sensitivity and high measurement bandwidth. However, cooling in proximity to coherent atomic state evolution can degrade performance in compact systems, due to decoherence. This study demonstrates an inertially sensitive matter-wave interferometer in a three-dimensionally-cooled atomic beam that mitigates decoherence while operating continuously. The technique could enable compact atom-interferometer sensors that measure continuously and with high sensitivity on dynamic platforms. read more
