Abstract
A gas cell for a miniature atomic frequency standard. The gas cell functions not only to contain the cesium vapor, but also as a resonator for the microwave signal used to excite the vapor. By combining the functions of gas cell and resonator into a single structure, and by taking advantage of the intensity of light available from a laser diode, the overall size of an atomic frequency standard can be reduced by two orders of magnitude when compared to prior art devices of comparable accuracy.
