A beam shaper array assembly including a beam source that provides a plurality of beams having a low fill factor profile. The assembly also includes an input beam shaper array having cells positioned adjacent to each other, where each cell includes an input beam shaper that receives one of the plurality beams and is shaped to cause the beam to expand as it propagates away from the input array to be converted from the low fill factor profile to a high fill factor profile. The assembly further includes an output beam shaper array having cells positioned adjacent to each other, where each cell includes an output beam shaper that receives one of the converted beams and is shaped to cause the beam to stop expanding so that the output array provides a plurality of adjacent beams with minimal overlap and a minimal gap between the beams.
