More Information
Summary:A light source device comprises a waveguide, an electrodeless lamp, a probe, and conversing means. The waveguide is formed to contain a medium enabling a microwave to resonate and has a surface and an aperture cavity with an aperture opened at a predetermined position of the surface. The electrodeless lamp is loaded in the aperture cavity in a state where part of the electrodeless lamp is protruded from the surface of the waveguide so that the part of the electrode lamp emits light in response to applying the microwave to the electrodeless lamp. The probe supplies a high-frequency signal to the waveguide so that the high-frequency signal is converted to the microwave in the waveguide. The converging means is disposed on the surface of the waveguide to face the aperture cavity and utilizes all the light emitted from the part of the electrodeless lamp to converge the light.
