Abstract
In some variations, a vapor-cell system comprises: a vapor-cell region configured to allow at least one vapor-cell optical path into a vapor phase within the vapor-cell region; a first electrode disposed in contact with the vapor-cell region; a second electrode that is electrically isolated from the first electrode; and a transparent ion-conducting layer interposed between the first electrode and the second electrode, wherein the transparent ion-conducting layer is optically transparent over a selected optical band of electromagnetic wavelengths. Some embodiments provide a magneto-optical trap or atomic-cloud imaging apparatus, comprising: the disclosed vapor-cell system; a source of laser beams configured to provide three orthogonal vapor-cell optical paths through the vapor-cell gas phase, to trap or image a population of cold atoms; and a magnetic-field source configured to generate magnetic fields within the vapor-cell region. Methods of use are also disclosed herein.
