Abstract
A semiconductor laser device is bonded to a heat sink. The semiconductor laser device contains a stripe structure having a width equal to or greater than 10 micrometers, and including a first optical guide layer of a first conductivity type, an active layer, and a second optical guide layer of a second conductivity type. A total thickness of the first and second optical guide layers is equal to or more than 0.5 micrometers. The semiconductor laser device is soldered onto the heat sink at a surface of the semiconductor laser device where the surface located is farther from the active layer than other surfaces of the semiconductor laser device.
