Abstract:
A light emitting apparatus includes: a laser element which emits laser light; a light emitting section which generates fluorescence in response to the laser light emitted from the laser element; a parabolic mirror which reflects the fluorescence generated by the light emitting section; and a multilayer filter which transmits the laser light and reflects the fluorescence, the laser element being provided outside the parabolic mirror, the parabolic mirror being provided with a window part through which the laser light passes, and the multilayer filter being provided so as to cover the window part.
