摘要： A laser beam printer is provided which is capable of compensating for the difference in diameter between dots every colors and preventing unintentional coloring of the boundary between colors. In a conventional light source used for a printer, a spot diameter thereof is small upon low output and large upon high output. However, in a semiconductor laser device of the present invention, which is used for a light source for a printer, the spot diameter of the light source is controlled so as to be large upon low output and small upon high output. It is thus possible to keep the spot diameter of the laser light source constant. As a result, an irregular color-free laser beam printer can be materialized.

摘要： An optical arrangement for an optical scanning apparatus which can record a plurality of high precision information concurrently, provides for a laser beam emitted from a single light source to be polarized in two polarization directions, and each of the two polarized beams is further imparted with different information according to its polarization direction. Then, the two polarized beams are used for scanning over a photosensitive member to concurrently record respective information at different positions on the photosensitive member. In order to suppress induced light fluctuation depending on an incident angle of light on the beam splitter, an optical rotation means is provided in the optical system, such that a desired optical rotation control can be obtained corresponding to the incident angle on the beam splitter, so as to compensate for the fluctuation of light whereby the beam splitter can be arranged to be free of the influence of the incidence angle of the beam.

摘要： In a laser beam scanning apparatus, first and second laser beam emitters emit a laser beam polarized in a specific direction and a laser beam polarized in the direction orthogonal with this specific direction. A prism passes a laser beam emitted from the first laser beam emitter but reflects a laser beam emitted from the second laser beam emitter, and amalgamates two laser beams emitted from the first and second laser beam emitters in almost the same direction. A rotating polygonal mirror and a scanning lens simultaneously scan on a scanned plane two laser beams amalgamated by the prism. A 1/4 wavelength plate is inserted between the rotating polygonal mirror and the prism to change the laser beam from the prism from a linearly polarized state to a circularly polarized state. By the above arrangement, a difference of reflection factors between two laser beams incident to the rotating polygonal mirror can be eliminated so that two uniform laser beams can be scanned at the same time.

摘要： An optical integrated circuit and an optical apparatus used in optical communication or an opto-electronics apparatus such as an optical disk recording apparatus, in which various kinds of aberration caused by wavelength variation of a light source when a semiconductor laser is used as the light source. An aberration correcting grating having such grating pitches as to nearly satisfy the Bragg condition preferably with respect to a certain wavelength of the semiconductor laser beam is used. As a result, lowering of incidence (entrance) and radiation (exit) coupling efficiencies of the grating coupler and aberration such as chromatic aberration can be prevented. Even if a multi-mode semiconductor laser is used as a light source, the characteristics of the optical integrated circuit and optical apparatus do not vary largely.

摘要： An optical scanning apparatus has a scanning lens with a rotationally asymmetric aspheric surface having individual curvature radii in the main scanning direction and in the sub-scanning direction. The curvature radius in the sub-scanning direction is asymmetrically increased in the lateral direction with the distance from the optical axis. A field curvature aberration which may be generated in the sub-scanning direction on the scanning surface due to an oblique incident of optical beams on the rotating polygonal mirror or the movement of the reflective surface caused by rotation of the rotating polygonal mirror is compensated for by the scanning lens and the focusing properties of the system can be kept at a level of high resolving power.

摘要： An optical pickup comprises at least a semiconductor laser, a waveguide optically coupled with the semiconductor laser for propagating therein a light from the semiconductor to guide it to a recording medium and a light deflector element provided on the waveguide for deflecting the light propagated in the waveguide by means of a surface acoustic wave. A multi-mode oscillation laser capable of stably operating in longitudinal modes the number of which is not larger than 5 is used as the semiconductor laser. The semiconductor laser is disposed in proximity to the waveguide at a distance not larger than 1 .mu.m, thereby inputting the light from the semiconductor laser into the waveguide with a high efficiency. A frequency applied to the light deflector element may be changed upon change between a read-out state and a write-in state so that a light spot on the recording medium is held at a predetermined position (track or address). In the case where a grating is used as a light coupling element between the waveguide and the exterior thereof, a hologram grating is disposed in a path of the light derived through the light coupling grating from the waveguide to the exterior thereof so that a chromatic aberration produced at the light coupling grating due to a change in wavelength of the semiconductor laser is cancelled by that produced at the hologram grating.
