    摘要： A blue-violet semiconductor laser device has a first p-electrode formed on its upper surface and a first n-electrode formed on its lower surface. A red semiconductor laser device has a second n-electrode formed on its upper surface and a second p-electrode formed on its lower surface. An infrared semiconductor laser device has a third n-electrode formed on its upper surface and a third p-electrode formed on its lower surface. Solder films are partially formed on the upper surface of the first p-electrode in the blue-violet semiconductor laser device. Two of the solder films are formed with a predetermined distance between them on the upper surface of the first p-electrode. This results in a portion of the first p-electrode being exposed. The first, second and third p-electrodes of the blue-violet semiconductor laser device, red semiconductor laser device, and infrared semiconductor laser device are common electrodes.

    摘要： Second and third p-side pad electrodes are formed on an insulating film of a blue-violet semiconductor laser device on both sides of a first p-side pad electrode. The second p-side pad electrode and the third p-side pad electrode are formed separately from each other. Solder films are formed on the upper surfaces of the second and third p-side pad electrodes respectively. A fourth p-side pad electrode of a red semiconductor laser device is bonded onto the second p-side pad electrode with the corresponding solder film sandwiched therebetween. A fifth p-side pad electrode of an infrared semiconductor laser device is bonded onto the third p-side pad electrode with the corresponding solder film sandwiched therebetween. The second and third p-side pad electrodes are formed separately from each other, so that the fourth and fifth p-side pad electrodes are electrically isolated from each other.
