Abstract:
A method of printing images with a printer that has a scanner and said printer utilizes a polarized multimode laser beam provided by an emitting aperture of a multimode laser, said method comprising the steps of:changing polarization of a portion of a cross section of said multimode laser beam, so that said multimode laser beam comprises a first portion with one polarization and a second portion with a different polarization;at least partially superimposing said first portion of said multimode laser beam onto said second portion of said multimode laser beam, thereby forming a superimposed laser beam;forming a printing spot with said superimposed laser beam;deflecting said superimposed laser beam along a scan line across a recording material so that a scan direction corresponds to a long dimension of the emitting aperture; andtranslating the recording material in a direction perpendicular to said scan line.
