Abstract
Photo-lithographical laser ablation was demonstrated by laser ablation using a femtosecond laser system with a lithographic optical system. Among them, laser beam passed through a mask and the pattern was imaged on the film by a pair of convex lenses. As a result, the film was lithographically ablated, and micron-sized patterns were generated in a single shot. Fringes were generated outside the ablated patterns with defocusing or larger laser fluence. The resolution of generation was 13 μm, and the narrowest width of a generated line was about 4 μm. In addition, transmission gratings were used instead of a mask, and nano-sized periodic structures were generated.
