Abstract

Laser surface micro machining has attracted a worldwide attention due to the possibility to obtain micro and submicrometric structuring on various substrates with the flexibility of the laser irradiation tool. Many application fields are impacted by the possibility to structure the surface at the micro and submicrometric level, mostly related to adding functions to surfaces like wettability, optical properties and cellular differentiation [1-3]. When using ultrafast laser pulses for surface structuring, the low onset of thermal effects at low repetition rate enlarges the laser process parameters that generates a wide variety of micro and nano structures.
