    摘要: A semiconductor laser device that is suitable for mass production, that permits an improved wire layout, and that permits miniaturization includes leads disposed through each of two side faces of an insulating frame member so as to run from outside to inside the insulating frame member, an LD and a light-receiving element mounted inside the insulating frame member, and wires laid inside the insulating frame member so as to connect the leads to the electrodes of the LD and the light-receiving element. Inside the insulating frame member, the tip of one lead is extended farther inward than the edge of an element mount portion that faces the tip of another lead that is disposed through the same side face of the insulating frame member.

    摘要: An optical pick-up apparatus and a semiconductor laser apparatus which can suppress reduction of optical utilization efficiency for the laser light emitted from the semiconductor laser element. When a laser light which is emitted from a laser element for DVD and whose polarization direction is perpendicular to a direction of a groove of the polarization grating is incident on the polarization grating, the polarization grating does not diffract the laser light and transmits the laser light as zero-order diffraction light. Consequently, all of the laser light emitted from the laser element for DVD can be used for reading information signal of DVD and detecting FES and TES. This enables reduction of optical utilization efficiency arising by diffracting action of a grating used for detecting TES of CD in a conventional optical pick-up apparatus to be suppressed.

    摘要: A semiconductor laser device, with which a compact and thin optical pickup can be realized, is provided. On the top surface of a supporting member, there is formed an element mounting area for mounting a series of elements including a semiconductor laser element, and a light detecting element which detects a laser beam emitted from the semiconductor laser element and reflected by a surface of an outside optical disc so as to be re-entered. An optical path from the semiconductor laser element to the surface of the optical disc includes a vertical optical path advancing from the element mounting area of the supporting member in an approximately vertical upward direction. On a pair of right and left opposing ends of the supporting member, arcuate curved outer surfaces are formed, respectively, so as to fit the supporting member into an installation hole, for a semiconductor laser device, having arcuate curved inner surfaces. These curved outer surfaces are formed of arcs having the vertical optical path as the central axes, and are so formed that the curvature radiuses of the right and left arcs are different.
