Abstract

See full text

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.
