Abstract
A laser writing apparatus includes a laser light source which directs an expanded beam of laser light onto a two-dimensional phase grating. The phase grating splits the beam into a two-dimensional array of individual bundles of collimated light or beamlets. Each individual row of beamlets is reflected by a single strip mirror toward the surface on which a pattern is to be written. By moving the surface under the beams at a selected angle, multiple parallel lines can be written simultaneously on the surface.
