Abstract:
1. A semiconductor laser device comprising: a semiconductor laser element array with a multi-beam structure including a semiconductor substrate, a cathode electrode of a first conductivity type formed on a first surface of the semiconductor substrate, a semiconductor layer formed on a second surface of the semiconductor substrate and having a plurality of light-emitting portions therein, anode electrodes of a second conductivity type formed above each of the plurality of light-emitting portions, and metal layers formed on each surface of the anode electrodes, wherein each of the metal layers is bonded to a first surface of a submount via a bonding material, thereby mounting the semiconductor laser element array on the submount, and central positions of the metal layers in a width direction are intentionally displaced with respect to central positions of the underlying light-emitting portions in a width direction.
