| 英文摘要 | A self-aligned type, high-power semiconductor laser is provided which exhibits multi-longitudinal mode oscillation in the low-power operation (at a light power output of, for example, 3 mW) through it is of a refractive index guiding structure capable of single transverse mode oscillation in up to the high-power operation. Specifically, the semiconductor laser is of an AlGaAs system and has a waveguide mechanism resulting from complex refractive index, and wherein a current-blocking layer is 2000 to 6000 ANGSTROM thick. |
