Atomic clocks and magnetometers with vapor cells having condensation sites in fluid communication with a cavity to hold a vapor condensation away from an optical path

摘要

A vapor cell for installation in an atomic clock or a magnetometer. The vapor cell includes a top plate, a center plate, and a bottom plate defining a cavity for passing light along an optical path. The vapor cell includes one or more condensation sites to trap condensed vapor in order to avoid blockage of the optical path.
