英文摘要 | PURPOSE:To reflect returning light of a laser beam in a desired direction without connection with a laser device and to reduce noises caused by the returning light, by providing a tilted reflecting surface on an edge of a substrate near a resonator edge side which emits a laser beam of a semiconductor laser device. CONSTITUTION:A current constriction laser 16 of n-type GaAs is formed on a main surface of a substrate 15 of p-type GaAs of a semiconductor laser device 1, and the layer thereof is divided with a striped groove 17 along the center line. A p-type clad layer 18, an active layer 19, an n-type clad layer 20 and a cap layer 21 are formed one by one on the layer 16 and the exposed substrate 15. A resonator 24 is formed opposite to the layer 19 and the groove 17. The resonator edge side 3 is exposed at an edge side 2 of the device 1 then a laser beam 4 is emitted from the edge side. A reflecting surface 12 tilting against the edge side 2 which reflects returning light 5 of the laser beam 4 partially to the rear of the substrate 15 which is opposite to the groove 17. The reflecting surface 12 is provided on the substrate 15 which is spaced by a predetermined distance from the resonator 24 and a sub beam 8 is set at a predetermined space. |
