Depiction of miniaturized atomic beam source. (a) Schematic of the Rb beam source. (b) Image of assembled device. (c) Rb fluorescence spectrum measuring the transverse velocity distribution of the atomic beam, and Rb absorption spectrum measuring the Rb vapor density feeding the channel array. A saturated absorption spectrum from a natural abundance Rb cell is included for reference.

Chip-Scale Atomic Beam System

NIST Inventors
Elizabeth Donley , John Kitching and William McGehee
The invention is a device for creating a collimated atomic beam in an evacuated vacuum package fabricated from lithographically defined or machined, planar structures and with components to source atomic vapor and passive pumps to maintain vacuum conditions. We have developed a chip-scale system for
Schematic of magnetometer/gyroscope shows layers with photodetectors on top and laser at bottom.

Compact Atomic Magnetometer and Gyroscope

NIST Inventors
John Kitching and Elizabeth Donley
The NIST Compact Atomic Magnetometer is based on a diverging (or converging) beam of light that passes through an alkali atom vapor cell and that contains a distribution of beam propagation vectors. The existence of more than one propagation direction permits longitudinal optical pumping of the
