Abstract: The formation of slits with very high aspect ratios is critical for the production of additively manufactured parts for advanced electric drives. In this work, high-speed synchrotron X-ray imaging is utilized to observe slit/groove formation in stainless steel using ultrashort laser pulses. The results reveal that, under the pulse conditions employed here, a narrow, deep slit or groove can be created by the eventual consolidation of micro-holes which are generated in the early stages of the laser-material interaction. The success or otherwise of this micro-hole consolidation has a complex relationship to the process parameters.
