  • Semiconductor laser apparatus
    Patent number: 5367530
    Abstract: A semiconductor laser device and a beam receiving device are mounted on a lead. The beam receiving device receives a sub beam irradiated from the semiconductor laser device. At an edge of the lead, concave portions are provided for positioning with an optical part which receives a laser beam irradiated from a main irradiating surface provided at the front of the semiconductor laser device. The beam optical axis of the semiconductor laser device is situated at a position higher than the position of a beam receiving surface of the beam receiving device is situated. A transparent resin covering from the rear surface of the semiconductor laser device to the beam receiving surface of the beam receiving device and containing a dispersing agent, or a molding resin made of an ultraviolet hardened resin and containing the dispersing agent is provided.
