Abstract : An adjustable linear integrating mirror for producing spatially uniform beam areas of high power lasers. The mirror is formed by a plurality of thin solid rectangular blocks made of a highly reflective metal with one thin face ground to a flat mirror finish. The blocks are assembled one upon the other with their mirror faces in alignment and held together at their ends by strips of spring steel. Wedge-shaped spacers are inserted between their free ends opposite the mirrored face to produce small angular rotations of each mirrored block. The spring steel should have sufficient tension to secure the wedges in place; however, if necessary, clamps may be used to hold the back ends together to secure the wedges in place. The angular setting of the mirrored blocks will determine the amount of overlay of the reflected laser beam. Fine tuning for a specific overlay may be performed by varying the depth of the wedges which varies the angular setting of each mirrored block section. (Author)
