Abstract

There is provided a light source apparatus and projector having the light source apparatus, said light source apparatus comprising: a laser module where first semiconductor laser(s) and second semiconductor laser(s) which emits a light of the wavelength different from that of said first semiconductor laser(s) are placed such that the emitting direction of each semiconductor laser is approximately the same and a short axis direction of a far field pattern of each semiconductor laser is approximately the same, and an optical multiplexing component which a light which exits from said laser module enters without being converged, wherein said first semiconductor laser(s) and said second semiconductor laser(s) are placed in linear symmetry in said short axis direction at the exit surface of said laser module.
