A surface emitting semiconductor laser array includes multiple light-emitting portions arranged in a one-dimensional or two-dimensional array, each of the light-emitting portions including, on a substrate, an active region and a current funneling portion between first and second reflection mirrors, and a light-emission aperture above the second reflection mirror, laser beams being simultaneously emitted from the multiple light-emitting portions. At least one of the multiple light-emitting portions has a near field pattern different from those of other light-emitting portions.
