Abstract
An atomic maser comprises a walled enclosure (76) defining a resonant cavity (4), and a storage bulb (8) for storing a medium capable of stimulated emission. The storage bulb is a sapphire cylinder (70) that is open at both ends and has two closure members (71,72) for closing the open ends. The closure members are made substantially of titanium and have a coating (73,74) of polyfluoroethene formed on their inner surfaces. At least one of the closure members (71,72) forms part of the walled enclosure.
