Abstract

To solve a special task of laser-beam material treatment, a new diffractive element was designed, fabricated and investigated, which converts a given single-mode CO ₂-laser beam into a ring-shaped intensity distribution in the working plane. This was accomplished by application of refined ray-tracing methods and an enhanced micro technology using e-beam generated masks. Relevant steps of calculation and manufacturing of these masks are outlined. First results of measured intensity distribution demonstrate a good conformity with results of computer simulations.
