ABSTRACT:
A time division multiplexed laser emits two beams of the same wavelength but orthogonal polarization or two beams of different wavelengths from a single laser source for use in a multiple beam raster output scanning system. The multiple beam raster output scanning is obtained from a single raster scanning system (ROS) with a rotating mirror, beneficially a polygon mirror, and a single set of scan optics for use in single or multiple station printers. A plurality of the coaxially overlapping laser beams from the same laser source are deflected using a common mirror surface area and laser beams containing different channels of data signals are subsequently separated by a plurality of dynamic and static beam separators based on polarization or wavelength. The channels of the separated laser beams are directed onto associated photoreceptors.
