Abstract
An apparatus emits a laser light beam with a first aspect ratio of etendue R, wherein the optical invariant with respect to a first direction is less than half the optical invariant with respect to a second orthogonal direction. A first cylindrical lens collimates the beam in the first direction. A second cylindrical lens collimates the light beam in the second direction. A bisecting reflective surface has an edge that splits the collimated beam into undeviated and first deviated beam paths. A folding reflective surface redirects the first deviated beam path back toward the bisecting reflective surface, optically parallel with and displaced from the undeviated beam path with respect to the first direction. At least a portion of the redirected first deviated beam path passes the edge and combines with the undeviated path to form an output beam having a second aspect ratio of etendue Rnot equal to R.
