    摘要： A laser beam emission apparatus that may be used as a universal optical pickup laser light source. The apparatus may be used in various applications including recording/reproduction of data to/from various types of optical disks in various recording/reproducing modes. The apparatus includes a first semiconductor laser chip that emits a first laser beam at a first wavelength, and a second semiconductor laser chip that emits a second laser beam at a second wavelength different from the first wavelength. The emitted second laser beam has a plane of polarization that is perpendicular to the plane of polarization of the emitted first laser beam. The apparatus further includes a polarized beam splitter that transmits one of the laser beams and reflects the other laser beam, and a semiconductor substrate that has the laser chips and the polarized beam splitter mounted thereon. The polarized beam splitter is mounted on the semiconductor substrate in a manner such that a polarized light division surface of the polarized beam splitter is perpendicular to the substrate surface of the semiconductor substrate, and the principal optical axes of the first and second laser beams intersect at a single point on the polarized light division surface and also lie in the same plane. The plane is positioned apart from the substrate surface of the semiconductor substrate, and is perpendicular to the polarized light division surface of the polarized beam splitter.

    摘要： An optical unit with shake correcting function may include a movable module having a lens, a fixed body supporting the movable module, a shake detection sensor for detecting shake of the movable module, and at least one pair of magnetic drive mechanism for shake correction which is structured on both sides of the movable module so that the movable module is swung with respect to the fixed body on the basis of detection result of the shake detection sensor to correct the shake of the movable module. The magnetic drive mechanism for shake correction is disposed so that a shake correction magnet is held by the fixed body and a shake correction coil is held by the movable module. Further, a shake correction coil may be disposed in a first region, where magnetic lines of force generated by a shake correction magnet are directed in directions generally going away from a supporting point part and/or a second region where magnetic lines of force generated by the shake correction magnet are directed in directions generally going toward the supporting point part.
