  • Patent number: 7894052
    Abstract: A laser beam oscillated from a laser source is folded in its path by first and second plane mirrors and enters a beam expander. The surface of each plane mirror is deteriorated with illumination by the laser beam and the reflectance is reduced. To avoid a light quantity of the laser beam entering the beam expander from being reduced below a reference value, when the laser beam is illuminated over a certain time, a position on each of the first and second plane mirrors at which the laser beam is illuminated is changed by a structure for rotating and/or translating a reflecting surface of each plane mirror on a plane, which includes the plane mirror, while an optical axis is kept same. Thus, the useful life of each plane mirror can be prolonged without displacing the optical axis.

  • Patent number: 7729400
    Abstract: An external cavity type semiconductor laser that has a larger output and a more excellent single mode characteristic than a conventional external cavity type semiconductor laser is provided. The external cavity type semiconductor laser has a laser diode 11, a window glass 16, a grating, and a lens. The external cavity type semiconductor laser has several modifications over the conventional one. A first modification is that the window glass 16 is inclined to a beam emission surface 19 of a laser diode 11 for a predetermined angle. A second modification is that arrangements of the laser diode 11 and so forth are adjusted so that a S wave reaches the grating. A third modification is that when an output power of the laser diode 11 is 45 mW or less, a kink is suppressed.

    Abstract: A laser beam emitted from a laser light source is divided into two laser beams, a 2-dimensional spatial modulation is performed to one of the two divided laser beams based on recording information, the modulated laser beam is projected as signal light onto a recording medium, the other laser beam is projected as reference light onto the recording medium, and the recording information is recorded onto the recording medium. The recording information recorded on the recording medium is reproduced based on the laser beam transmitted through or reflected by the recording medium. An optical system includes: a rotatable mirror portion for guiding the reference light to the recording medium at an angle according to the direction of its reflecting surface; a vibration proofing member coupled with a rear surface of the mirror portion; and a driving mechanism which decides an angle position of the mirror portion and is coupled with the mirror portion.
