ABSTRACT:
In a multi-beam laser light source constructed of a laser array in which a plurality of independently drivable laser elements are arranged in an equiinterval, and a lens array in which a plurality of lenses employed in accordance with the plural laser elements are arranged in an equiinterval, a laser array interval of the laser array is different from a lens array interval of the lens array.
Further, the multi-beam semiconductor laser array is so constructed that a gradient-index type planar micro lens array is closely fitted to a laser beam projection edge of a semiconductor laser array in which a plurality of independently drivable semiconductor laser elements have been arranged on the same substrate.
