Abstract: A method using femtosecond laser for nano precision preparation. Initial damage nanoholes formed by using femtosecond laser multiphoton excitation are used as a seed structure, and the energy and polarization state of subsequent laser pulses are adjusted in real time, such that uniform and directional optical near-field enhancement is generated near the seed structure and finally the high-precision removal of machined materials is realized. Benefiting from the high localization of near-field spot energy in space, the method uses femtosecond laser pulses having the wavelength of 800 nm to achieve a machining accuracy having the minimum linewidth of only 18 nm, and the linewidth resolution reaches 1/40 of the wavelength; and the method using femtosecond laser for nano precision preparation does not need a vacuum environment, having good air/solution machining compatibility.
