    摘要: An optical fiber array is constructed by using a plurality of laser modules, which guide a laser beam emitted from a semiconductor laser of a blue color wavelength to an optical fiber, such that beam emitting ends of respective optical fibers are aligned in one row at an equal interval, and the laser beam being output from the optical fiber array is used as a multibeam of an optical recording apparatus. A relative refractive index difference of the used optical fiber is set between 0.1% to 0.2%, and a core diameter is set to 4.5 μm or less, and also a mode field diameter of the optical fiber, i.e., a diameter of a beam spot emitted from the optical fiber is set to 3 μm or more.

    摘要: A multi-beam generating device has plural semiconductor lasers, optical fibers to propagate laser beams generated by the semiconductor lasers, an optical fiber array to propagate the laser beams passed through the optical fibers, and an optical waveguide device provided with waveguides to propagate the laser beams having passed through the optical fiber array. Each of the waveguides has a core layer and a clad layer; a pitch between adjacent waveguides in the arrangement is narrower on the output section side where the laser beams emit than on the input section side where the laser beams enter; a width of the core layer is narrower in the transverse direction that is the direction of the arrangement of the waveguides than in the vertical direction; and a difference in refractive index between the core layer and the clad layer is larger in the transverse direction than in the vertical direction.

    摘要: A semiconductor laser module includes a laser holder, a semiconductor laser, a sleeve, an optical fiber, an annular member, and a flexible member. The laser holder has an end portion and is formed with a through-hole opened on the end portion. The semiconductor laser is provided on the laser holder and has a light-emitting portion for emitting a laser beam passing through the through-hole. The sleeve is fixed to the end portion so as to block the through-hole and is formed with an insertion hole. The optical fiber is disposed in the insertion hole and has an incident face. The laser beam is capable of entering the incident face. The annular member is provided on the end portion of the laser holder to encircle outside of the sleeve to be separated from the sleeve with a space between the annular member and the sleeve. The flexible member is affixed to the sleeve and the annular member for covering the space.

    摘要: In a laser printing device in which a laser beam is deflected in a scanning mode while its intensity is being modulated, to record a halftone image on an optical recording material, the scanning laser beam is oscillated in a direction substantially perpendicular to the scanning direction within one pitch of the scanning line formed on the optical recording material, and the oscillation of the scanning laser beam is changed in amplitude by a signal provided by a computer, whereby a halftone image is recorded with high accuracy.
