Patent ID: 7965044

Claim:
An optical source device comprising: a solid high frequency oscillating unit that outputs a high frequency signal; a waveguide unit that receives the high frequency signal output from the solid high frequency oscillating unit and radiates the received high frequency signal as a microwave; and a light emitting unit that emits light by the microwave radiated from the waveguide unit, wherein the waveguide unit includes an antenna unit that radiates the received high frequency signal as the microwave, and a container that contains a dielectric material, accommodates the antenna unit, and has a space surrounded by a first reflective surface that reflect the microwave radiated from the antenna unit and a second reflective surface that correct the microwave reflected by the first surface, and the light emitting unit includes a non-electrode light emitting tube that is disposed in a region where the microwave is collected by the second surface, and has a portion extending to the outside of the container and a light emitting material is sealed therein for emitting light by the microwave, and a reflective unit that reflects a light beam emitted from the non-electrode light emitting tube using the extending portion of the non-electrode light emitting tube as a focal point or an approximate focal point.
