Abstract

Abstract The combination of diffractive optical elements or spatial light modulators with fully synchronized galvo scanners offers a possibility to scale up machining processes with ultra-short pulses to several 100 W of average power with minimal thermal impact. This will be demonstrated with the high-rate applications multi-pulse drilling on the fly and material removal with special intensity distributions up to an average power of 162 W and a removal rate of 16.5 mm3/min. Based on the experimental results strategies to achieve drilling rates of several 10,000 holes/s or removal rates of multiple 10 mm3/min will be discussed.
