The present invention provides a laser optic module which includes a laser source which generates a laser beam, a beam guide which includes a light path with a sidewall which is a reflective surface inside, inputs the laser beam to the light path, and guides the laser beam, and a fluorescent material which is formed on the end of the light path and emits fluorescent light by the laser beam. The width of the light path is formed according to a full width at half maximum (FWHM) of the laser beam in a position where the laser beam is inputted to the fluorescent material. Thereby, luminous efficiency is improved by directly using the laser beam and the size of the laser optic module is reduced by a simple structure. |
