SEMICONDUCTOR LASER DEVICE

摘要

PROBLEM TO BE SOLVED: To improve the quality of a laser beam in a lateral direction. SOLUTION: An electrode stripe 10 is formed by inclining it in a face in a lateral direction against an oscillation optical axis Q of the laser beam. Thus, the quality of the laser beam in the lateral direction can considerably be improved and luminance can be improved much more with a single electrode stripe 5 even in a semiconductor laser device having a gain waveguide structure in the lateral direction.
