Abstract
A sub-substrate, a blue-violet semiconductor laser device, an insulating layer, and a red semiconductor laser device are stacked in order on a support member through a plurality of fusion layers. The insulating layer is stacked on an n-side pad electrode of the blue-violet semiconductor laser device, and a conductive layer is formed on the insulating layer. The red semiconductor laser device is stacked on the conductive layer through a fusion layer. The conductive layer is electrically connected to a p-side pad electrode of the red semiconductor laser device. The n-side pad electrode of the blue-violet semiconductor laser device and the n-side pad electrode of the red semiconductor laser device are electrically connected to each other.
