Abstract
Compared with light emitting diodes (LEDs), laser diodes (LDs) are attractive for applications in which size and radiance matter. The elliptical, highly divergent, and astigmatic beam characteristics make LD beams difficult to handle. Compare with conventional techniques, freeform optics can precisely control the LD beam. However, freeform optics design for LD beam shaping is a very difficult inverse problem. A simple and efficient method is provided to iteratively construct freeform surfaces for achieving difficult LD beam shaping tasks.
