Abstract

Simultaneous scanning of multiple beams is an effective method to realize high-speed and high-resolution laser printer. For producing multiple beams, we have been developing an optical fiber array method and recently we could successfully demonstrate a laser printing using the optical fiber array for five beams. The wavelength of diode lasers is 640nm at which the photoconductor drum has sensitivity. The fiber array has a spacing of 0.15mm and each fiber emits a circular Gaussian beam of 5μm in diameter. In the arrayed fibers, the alignment error vertical to the array direction is suppressed below 0.4μm. In the optics, the curve of scan lines and print position errors in scan direction caused by the wavelength differences among diode lasers are suppressed negligibly small due to the achromatized design.
