Abstract
AlGaInP system laser device () and AlGaAs system laser device () are arranged so that respective stripes () are parallel to each other. The AlGaInP system laser device () is placed to (011) plane () side from the centerline of the substrate and the AlGaAs system laser device () is placed to the (0{overscore (1)}{overscore (1)}) plane () side from the centerline of the substrate when viewed from the main emitting plane (01{overscore (1)}) () side of laser light. Substrate () is an off substrate and inclines from the (0{overscore (1)}{overscore (1)}) plane () toward the (011) plane () with respect to the (100) plane at a certain angle (θ off) within the range of 2 degrees and 15 degrees. Optical axis Lof the AlGaInP system laser device () is parallel to optical axis Lof the AlGaAs system laser device () and approaches at an angle of about 0.5 degrees.
