ABSTRACT:
Novel designs for efficient coupling mechanism for the conversion of typical profile laser beams into J.sub.o -profile beams are presented. Several specific embodiments are provided which employ non-linear optical mechanisms in the conversion process, and other embodiments are provided which utilize holography in the conversion process.
