Abstract
A semiconductor laser apparatus includes: a semiconductor laser device for junction down mounting that includes a first light-emitting device region and a second light-emitting device region formed separately on a substrate. The first light-emitting device region and the second light-emitting device region in the semiconductor laser device each have a stack structure in which an n-type semiconductor layer, an active layer, and a p-type semiconductor layer are stacked in stated order. The first light-emitting device region includes a first electrode film located on the n-type semiconductor layer. The second light-emitting device region includes a second electrode film located on the p-type semiconductor layer. The first electrode film and the second electrode film are electrically connected to each other.
