Abstract
A light emitting sealed body includes: a housing containing light-emitting gas in an internal space; a first window portion which is provided to the housing and on which first light that is laser light for maintaining a plasma generated in the light-emitting gas is incident; a second window portion provided to the housing and from which second light that is light from the plasma is emitted; and a getter portion including a getter material and disposed in an irradiation region of the first light inside the housing.
Claims20
A light emitting sealed body comprising:
- a housing containing light-emitting gas in an internal space;
- a first window portion provided to the housing and on which first light is incident, wherein the first light is laser light for maintaining a plasma generated in the light-emitting gas;
- a second window portion provided to the housing and from which second light is emitted, wherein the second light is light from the plasma;
- and
- a getter portion including a getter material and disposed in an irradiation region of the first light inside the housing.
A method for driving a light emitting sealed body including a housing containing light-emitting gas in an internal space, on which first light that is laser light for maintaining a plasma generated in the light-emitting gas is incident and from which second light that is light from the plasma is emitted, and a getter portion including a getter material and being disposed in an irradiation region of the first light inside the housing, the method comprising:
- activating the getter material by irradiating the getter material with the first light;
- and
- generating the plasma in the light-emitting gas and emitting the second light.
