We describe a nonmechanical beam forming device which simultaneously provides the high precision beam deflection and beam spoiling required for narrow beamwidth laser communication systems. The device''s transmission is near unity and is composed of a liquid crystal optical phased array sandwiched between static phase plates. Device design and performance goals are described, along with the results of proof-of-concept experiments.
