Patent ID: 7680171

Claim:
A semiconductor laser device, comprising: a semiconductor laser element including stripe active regions for emitting laser beams; a base block on which wirings are formed, the wirings being electrically connected to stripe laser electrodes of said semiconductor laser element, respectively, the stripe laser electrodes corresponding to the stripe active regions being formed in proximity to a first surface of said semiconductor laser element, close to the stripe active regions; and a package for disposing said base block with said semiconductor laser element, said package including a connecting electrode part for connecting the semiconductor laser device to an external device, wherein an electric current is supplied to the stripe active regions from connecting portions between each of the laser electrodes and the wirings, a rear electrode is formed across a second surface of said semiconductor laser element, the second surface being formed in parallel to the first surface and opposing the first surface, respective ends of conductive wires are discreetly connected to the rear electrode at both ends and a middle portion of each corresponding stripe active region, and the respective other ends of the conductive wires are connected to the connecting electrode part.
