  • Patent number: 9092955
    Abstract: The present invention relates to a laser apparatus for inducing a photo-mechanical effect. More particularly, the present invention relates to a laser apparatus for outputting a pulsed laser beam and inducing a photo-mechanical effect by controlling pulse energy of the pulsed laser beam.
    Type: Grant

  • Patent number: 8810933
    Abstract: Disclosed are a lens unit and a method of manufacturing the same. The lens unit includes a lens part including a curved region having a predetermined curvature; and a support part including a hole, in which the lens part is installed, and attached to the lens part at a lateral side of the hole. The lens part having the curvature and the support part of the lens unit are formed in separate processes such that the hole is formed in the support part having the strength, and the lens part is formed by filling the hole with the lens part, so that the movement of resin caused by shrinkage of the lens part when the lens part is cured is inhibited, and the support part and the lens part does not form the layered structure, thereby allowing the lens unit to be formed with a thin thickness.

  • Publication number: 20050002310
    Abstract: Disclosed is a servo control method in a disk type holographic data storage apparatus such as a CD-ROM or a DVD-ROM, which has free insertion and extraction characteristics, and the holographic data storage apparatus using the same. Data pixels can be precisely read during the reproduction of the stored holographic data. When a holographic data storage medium having the stored data is rotated, the position of the reproduced holographic data may be deviated from the pixel position in a detector due to errors. A servo control method is conducted to correct the position of the data pixel in the detector. A flat glass is positioned in a 4-f lens system and an angle of inclination of the flat glass is adjusted. The angle of the reference beam is changed while the position of the reference beam is maintained. The light pick-up device may be downsized without using an expensive device such as an acoustic-optic modulator or galvano-mirror.
