A lighting system includes a microwave resonator ( 2 ) for generating a standing microwave in the internal space, and a gas cell ( 6 ) enclosing a medium is disposed in the internal space of the microwave resonator 2 . The lighting system excites the medium in the gas cell ( 6 ) by the standing microwave to generate light. The gas cell ( 6 ) is replaceably mounted on the microwave resonator ( 2 ). The generated light is output to the outside of the microwave resonator ( 2 ) through a light lead-out hole ( 26 ). Thereby, it is possible to provide a lighting system (including a gas laser) capable of emitting light efficiently with a compact and inexpensive device configuration and of achieving a long life. Moreover, it can also be used as a lighting system in the THz-wave region by enclosing the medium for generating light in the far-infrared region in the gas cell ( 6 ).
