摘要： Disclosed is an arrangement that enables to keep a relative positional relation between a beam for servo control and a beam for information recording/reproduction constant concerning focusing control and tracking control, even if the two beams are different from each other. An optical storage medium has a reflection surface for reflecting a first beam having a first wavelength, and reflecting a second beam having a second wavelength different from the first wavelength; and an information storage layer for recording information as an interference pattern by incidence of the first beam, or reproducing the information from a wave surface based on the interference pattern. The reflection surface is formed with plural marks or guide grooves usable in a tracking operation or a focusing operation by irradiation of the second beam. The information storage layer is partially formed, in advance, with a reference interference pattern which is reproduced when the first beam is irradiated, and which is used as a reference for correcting the relative positional relation between the first beam and the second beam.

摘要： A semiconductor laser light source 10 emits a laser beam for pumping. An optical resonator 2 includes a solid laser crystal 15 to be excited by the incident of a laser beam to oscillate a fundamental wave 20 and a pair of fundamental wave reflective coats 14, 16 arranged at the opposite sides of the solid laser crystal 15. A wavelength conversion element 18 converts the fundamental wave 20 into a plurality of harmonics 21, 22. The wavelength conversion element 18 is so arranged in the optical resonator 2 that the optical axis of at least one of the plurality of harmonics 21, 22 generated in the optical resonator 2 is made different from that of the fundamental wave 20 and the at least one harmonic 22 whose optical axis is made different is output substantially in the same direction as the other harmonic 21. By this construction, it is possible to stabilize a harmonic output and utilize a plurality of harmonics without increasing the number of parts.

摘要： Disclosed is a liquid crystal display device, which is capable of reducing a required response speed and increasing a pixel aperture ratio, as compared with a field sequential driving scheme. A unit pixel of a liquid crystal display panel is made up of a first sub-pixel adapted to allow only any two of red, green and blue lights to pass therethrough, and a second sub-pixel adapted to allow only a remaining one of the red, green and blue lights to pass therethrough, wherein one frame of image is time-divided into n pieces (wherein n is an integer of two or more), and respective image information about the two lights are applied to the first sub-pixel during every duration of the 1/n frame, while applying image information about the remaining one light to the second sub-pixel during a duration of the one frame of image. Further, the respective two lights are emitted during every duration of the 1/n frame in synchronization with applying the respective image information about the two lights, while continuously emitting the remaining one light during the duration of the one frame of image.
