ABSTRACT:
A microwave discharge light source device in which one side of a discharge space in which a plasma emission takes place is defined by a transparent dielectric member. A transparent microwave reflecting member is disposed in a position such as to face the discharge space through the dielectric member. A microwave having an electric field component in the direction of thickness of the dielectric member is introduced into the dielectric member through the coupling at an end surface of the dielectric member so that a microwave electric field is formed in the discharge space, and so that the plasma emission medium emits light by electric discharge. The light thus emitted is extracted through the transparent microwave reflecting member.
