The illumination system includes: a laser light source which emits a plurality of laser beams including beamlets along different optical axes; and a diffractive optical element which spatially averages the laser beamlets by superimposing the laser beamlets to remove speckles of the laser beamlets and which shapes each of the laser beamlets.
