ABSTRACT:
In a wavelength converting device including a light waveguide made of nonlinear optical material and outputting Cherenkov light, a reflecting mirror for reflecting guided light is provided at the end of the light waveguide. The light waveguide may include a light introducing portion and a curved light waveguide smoothly coupled with the light introducing portion. The light waveguide may have a Y-shaped structure including two light introducing portions partially parallel to each other, a junction part at which the two light introducing portions are smoothly joined together, and a linear light generating portion coupled with the junction part.
