ABSTRACT:
A raster output scanner (ROS) laser diode architecture produces plurality of laser beams, having dissimilar wavelengths and dissimilar polarizations which are passed through wavelength and polarization discriminating optics to alternately pass or reflect the beams that have been scanned by a single polygon mirror. Polarization of the beams is accomplished via post emission polarizers, such as, for example, half-wave plates. These separated beams then expose their associated photo-receptors, for example, of a multistation printer, with a rasterized image that is subsequently transferred to a support medium such as plain paper, and developed into an image.
