Antirelaxation Coatings for Vapor Cells

Abstract

In a general aspect, antirelaxation coatings are disclosed for coating the interior surfaces of vapor cells. In certain aspects, a vapor cell includes a dielectric body having interior and exterior surfaces. The interior surface defines a cavity in the dielectric body, and the exterior surface defines an opening to the cavity. The vapor cell also includes an antirelaxation coating that is disposed on the interior surface of the dielectric body and includes an organosilane material. The vapor cell additionally includes a vapor or a source of vapor residing in the cavity as well as an optical window that covers the opening to the cavity. The optical window has a surface bonded to the exterior surface of the dielectric body to form a seal around the opening. The vapor or the source of vapor includes alkali metal atoms.
