Abstract: Systems and methods for an optically dithered atomic gyro-compass are provided. In one embodiment, an inertial sensor comprises: a vacuum chamber containing a cloud of laser cooled alkali atoms, wherein the atoms are free to fall under the influence of gravity; a first set of laser sources applying a first set of laser beams into the cloud along a first axis; a second set of laser sources applying a second set of laser beams into the cloud along a second axis; wherein the first set and second sets of laser beams apply coherent laser pulses that separate a wave function of the atoms along trajectories defining a plane sensitive to rotation about an axis orthogonal to the plane; and wherein the first and second set of laser sources apply dithering to the axis by modulating a relative magnitude of the first laser beams with respect to the second laser beams.

Abstract: In an example, a chip-scale atomic clock physics package is provided. The physics package includes a body defining a cavity having a base surface and one or more side walls. The cavity includes a first step surface and a second step surface defined in the one or more side walls. A first scaffold mounted to the base surface in the cavity. One or more spacers defining an aperture therethrough are mounted to the second step surface in the cavity. A second scaffold is mounted to a first surface of the one or more spacers spans across the aperture of the one or more spacers. A third scaffold is mounted to a second surface of the one or more spacers in the cavity and spans across the aperture of the one or more spacers. Other components of the physics package are mounted to the first, second, and third scaffold.
