Abstract
An apparatus includes beam shearing optics situated to receive a collimated beam and to shear the collimated beam along a first direction so as to form a plurality of adjacent collimated beam portions, and homogenization optics situated to receive and homogenize the adjacent collimated beam portions along at least the first direction so as to produce a homogenized output beam. A method includes shearing a collimated beam having a beam parameter product (bpp) along an axis so as to form a plurality of sheared collimated beam portions, and arranging the sheared collimated beam portions adjacent to each other so that a line beam having a length and thickness that is formed with the light from the sheared collimated beam portions has a lower bpp associated with the line beam thickness than the bpp of the collimated beam along the axis.
