Abstract
A getter (50) situated in a cavity of a hollow structure (40-46), such as a flat-panel device, is activated by directing light energy locally through part of a hollow structure and onto the getter. The light energy is typically provided by a laser beam (60). The getter, typically of the non-evaporable type, is usually inserted as a single piece of gettering material into the cavity. The getter normally can be activated/re-activated multiple times in this manner, typically during the sealing of different parts of the structure together.
