ABSTRACT:
A method and apparatus for printing images. The optical output from a spatial multimode laser, which is multimode in one direction and is single mode in the orthogonal direction, is scanned parallel to the multimode direction. More specifically, according to one aspect of the present invention the printing apparatus includes a multimode laser having an emitting aperture that provides a laser beam. A scanner scans the laser beam from this laser along a scan line such that a long dimension of said emitting aperture corresponds to the scan direction. An optical system focuses the laser beam to a spot having a long dimension and a short dimension, such that the long dimension of the spot is along the scan direction.
