Lighting system
First Claim
1. A lighting system for generating light by exciting a medium such as gas or vapor, comprising:
- a microwave resonator having an internal space for generating a standing microwave;
a microwave supply means for supplying the microwave into the internal space of the microwave resonator; and
a gas cell enclosing the medium and disposed in the internal space of the microwave resonator,wherein the microwave generated by the microwave resonator is a standing wave of a linearly-polarized wave;
wherein the gas cell is disposed in a position corresponding to a maximum electric field strength of the standing wave in the internal space of the microwave resonator or in the vicinity thereof, and in a direction parallel to the direction of the linearly-polarized wave, andthe light is generated by exciting the medium in the gas cell using the standing microwave of the linearly-polarized wave generated in the internal space of the microwave resonator and wherein the generated light is output to the outside of the microwave resonator through a light lead-out hole provided in the microwave resonator.

Abstract
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).
