Abstract:
A method of beam shaping radiation from a laser diode comprising the steps of:receiving a laser beam into an optical element through an input surface; partitioning said laser beam along a longitudinal axis thereof into first and second longitudinal portions by internally reflecting said first longitudinal portion with a mirrored portion of an output surface of said optical element and transmitting said second longitudinal portion out of said optical element through an optically transmissible portion of said output surface; internally reflecting said first longitudinal portion of said laser beam with a mirrored portion of said input surface so as to cause said first longitudinal portion to be propagated toward said output surface substantially parallel to and laterally shifted from, said second longitudinal portion, said mirrored portion of said output surface oriented orthogonal to said mirrored portion of input surface; and transmitting said first longitudinal portion out of said optical element through said output surface.
