Abstract
A laser diode array produces one set of beams that are out of phase with those of another set of beams, with the beams of one set alternating with those of the other. The phase plate has first and second sets of regions, with the regions of one set alternating with those of the other. The phase plate is positioned in the near field of the beam pattern such that one set of beams passes through one set of regions and the other set of beams passes through the other set of regions. One set of regions changes the phase of the beams passing therethrough to create a substantially single lobed beam pattern in the far field.
