Abstract
A fluorescent molded body includes a first surface that receives incident light from a laser light source, a second surface that faces the first surface, first and second lateral surfaces each contacting the second surface at a blunt angle, and a phosphor layer that is excited by light from the laser light source to emit a specific light. A distance between the position where the first and second lateral surfaces meet the second surface is less than two times the wavelength of the second light, such that evanescent waves generated at the first and second lateral surfaces by the second light, are coupled together to be converted into output light.
