Abstract

Ultrafast laser ablation was applied to process 10-nm self-supporting membranes. The membranes were processed over tens of square micrometers by single-shot irradiation of two visible laser pulses, followed by the realization of periodic sub-microstructures. The fabricated geometry is dependent on the intensity distribution of the superposed input pulses, providing flexibility and facilitating practical micro- and nanoengineering. Ease of designing the processing parameters and speed of processing are the significant advantages of this method compared to focused ion beam (FIB) milling.
