Abstract
Some variations provide an alkali metal or alkaline earth metal vapor cell with a solid ionic conductor and intercalable-compound electrodes. The intercalable-compound electrodes are used as efficient sources and/or as sinks for alkali metal or alkaline earth metal atoms, thus enabling electrical control over metal atom content in the vapor cell. Some variations provide a vapor-cell system comprising: a vapor-cell region configured to allow a vapor-cell optical path into a vapor-cell vapor phase; a first electrode containing an intercalable compound capable of being intercalated by at least one element selected from Rb, Cs, Na, K, or Sr; a second electrode electrically isolated from the first electrode; and an ion-conducting layer between the first electrode and the second electrode. The ion-conducting layer is ionically conductive for at least one ionic species selected from Rb, Cs, Na, K, or Sr. The first intercalable compound is preferably a carbonaceous material, such as graphite.
