ABSTRACT:
A light source device includes: a plurality of light emitting elements that emit laser light; and a wavelength selective element that includes a light selective region functioning as a resonator mirror of the light emitting element by selecting light of predetermined selective wavelength from the laser light emitted from one of the light emitting elements and reflecting the selected light toward the light emitting element while allowing the remaining laser light to pass therethrough, and a base member having a plurality of the light selective regions so that the wavelengths of the light selected by the light selective regions are different from each other.
