Summary form only given.Atom interferometers have opened up new areas of fundamental and applied research. As well known from photon optics, multiple-beam interferometers offer an increased sensitivity on the relative phases between interfering waves. Very recently, first atomic multiple-beam interferometers were realized. These concepts are based on an atomic beam that is spatially split into coherent partial de Broglie waves, where the number of interfering waves is determined by the internal atomic multi-level scheme. We report on time-domain atomic interferometry within a two-level system.

We propose a new design of a multi-axis atom interferometer (AI) gyroscope based on a grating chip, which allows a single input laser beam for atomic trapping and coherent manipulation. Multiple AIs are formed by the input laser beam along with the other four diffractive beams generated by the grating chip. The rotation induced phase shifts from different input axes lead to different spatial interference fringes due to the modulation of the atomic velocity. With the point source interferometry (PSI) and the spatially resolved detection, multi-axis rotations may be measured by imaging the final atomic cloud after the interferometer sequence and decoding the information of spatial fringes from different input axes. Monte-Carlo based simulation are used for evaluating the proposed scheme and its application as a multi-axis gyroscope.
