<p>A compact multi-beam laser scanning system having a large bandwidth which is capable of being modulated at a high information rate. The multi-beam laser scanning system is applicable to a wide format, high resolution, high speed electrophotographic printing process and comprises apparatus for producing a plurality of modulated laser beams; multiple beam combiner apparatus disposed so as to have each of the beams incident thereon for combining the plurality of modulated beams to provide a plurality of output beams which are commonly aligned in a plane and have a fixed angular separation therebetween; and deflection scanning and focusing apparatus for providing the commonly aligned and angularly separated output beams with a scanning motion on an image plane.</p> |
