A dual-isotope atomic beam interferometer

Multi-isotope operation of atom interferometers can enable new practical capabilities such as concurrent and co-located interferometers exhibiting multi-axis or multi-scale-factor measurement, in addition to fundamental studies such as equivalence principle tests. We describe the development of a dual-isotope interferometer based on a continuously laser-cooled atomic beam. In addition, we provide an update on our development of a dualbeam atomic gyroscope using continuous, counterpropagating, 3D-cooled rubidium beams for inertial sensing applications.
