Abstract
A novel beam-forming and delivery technique for high-power laser beams for the generation of well-defined intensity distributions based on d iffractive optical elements is reported. It will be shown that nonline ar beam distortions can be minimized by applying this technique in the field of femtosecond-laser-based micro-machining. As a concrete ex am ple, the production of high-quality holes in metallic workpieces at at mospheric pressure will be discussed.
