Patent ID: 7724437

Claim:
A laser beam shaper to shape asymmetrical laser light beams generated by a light source in slow and fast axis directions, the slow axis being in a plane of a p-n junction of the beams, and the fast axis being in a plane perpendicular to the plane of the p-n junction of the beams, the laser beam shaper comprising: a first focusing element comprising an acylindrical lens located at a distance from the light source such that the beams in the direction of the fast axis are imaged directly onto an output plain of a beam shaper element; a first multi-segment element comprising a multi-edged prism, wherein surface segments of the first multi-segment element refract the asymmetrical light beams such that the refracted beams propagate non-uniformly in the direction of the fast and slow axis without overlapping with one another; and a second multi-segment element comprising a set of glass plates having input and output surfaces, wherein the first and second multi-segment elements separate and redistribute the light beams, and image the light source, in the direction of the slow axis.
