Abstract:
1. A semiconductor laser apparatus having two light emitting points, the semiconductor laser apparatus comprising: a substrate having a width and a center along a width direction; and two simple ridge stripe structures, each simple ridge stripe structure including a respective light emitting point directly opposite the corresponding simple ridge stripe structure, wherein both of the light emitting points of the corresponding simple ridge stripe structures are disposed at locations spaced from a line perpendicular to and passing through the center of the substrate, the light emitting points of the two simple ridge stripe structures are asymmetrically disposed with respect the line perpendicular to and passing the center of the substrate, and one of the light emitting points of the correpsonding simple ridge stripe structure is disposed at a distance along the width direction from the line perpendicular to and passing through the center of the substrate by a distance not larger than 15% of the width of the substrate.
