Abstract

Femtosecond lasers are available with an increasing energy per pulse. Their efficient exploitation without any decrease of quality is key. It could be done with beam-splitting and parallel processing. We present a fully reflective CANUNDA-SPLIT module used with a 100W 1030nm 500fs laser and a 100mm F-theta. The uniformity of the beams over the Field of View is presented. The drilling of stainless steel and Nickel cavities matrices, designed for tribological properties improvement, has been performed. The homogeneity of the cavities and the circularity are analyzed. These results paves the way to meter-scale area processing with a reduced processing time.
