Claim of US Patent No. 9,759,924

1. A system for shaping a beam comprising:
an emitter emitting spatially coherent electromagnetic radiation;
at least two birefringent displacers configured between said emitter and a target in at least two stages wherein said stages
define a fixed distance, wherein said at least two birefringent displacers further comprise a parallel input and output face
with an optical axis at 45 degrees thereof configured to split said coherent electromagnetic radiation into a plurality of
coherent parallel beams of electromagnetic radiation thereby producing a shaped wave front of said coherent parallel beams
of electromagnetic radiation; and

at least one wave plate configured in front of each of said at least two birefringent displacers.
