摘要： A light emitting sealed body includes a housing which stores a discharge gas in an internal space and is provided with a first window portion to which first light is incident and a second window portion from which second light is emitted. The housing includes at least one flow path which is partitioned from the internal space and extends toward at least one of the first window portion and the second window portion.

摘要： A light emitting sealed body includes a housing which stores a discharge gas and is provided with a first opening to which first light is incident and a second opening from which second light is emitted, a first window portion which includes a first window member allowing the first light to be transmitted therethrough and hermetically seals the first opening, and a second window portion which includes a second window member allowing the second light to be transmitted therethrough and hermetically seals the second opening. Each of the first window member and the second window member is hermetically fixed to the housing by a joining material. A protection layer which covers the joining material is provided at at least one of a first joining position between the first window member and the housing and a second joining position between the second window member and the housing.

摘要： A light emitting sealed body includes: a housing which stores a discharge gas and is provided with a first opening to which first light is incident along a first optical axis and a second opening from which second light is emitted along a second optical axis; a first window portion which hermetically seals the first opening; and a second window portion which hermetically seals the second opening. The housing is formed of a light shielding material which does not transmit the first light and the second light. An internal space is defined by the housing, the first window portion, and the second window portion and the internal space is filled with the discharge gas. The first opening and the second opening are disposed so that the first optical axis and the second optical axis intersect each other.

摘要： A light emitting unit includes a light emitting sealed body and a voltage application circuit. The light emitting sealed body includes a container to which laser light for maintaining plasma is incident and from which light from the plasma is emitted, a first electrode which includes a first discharge portion, and a second electrode which includes a second discharge portion. An end portion of the first discharge portion has a shape in which a thickness is thinned as it goes toward the second discharge portion and an end surface of the second discharge portion extends along a plane perpendicular to an extending direction of the first discharge portion. The voltage application circuit controls a potential difference between the first electrode and the second electrode by adjusting a voltage applied to at least the first electrode.
