Surface texturing of the carbon steel AISI 1045 using femtosecond laser in single pulse and scanning regime

► Determined surface damage threshold of the AISI 1045 for ten femtosecond laser pulses, Fth = 0.22 J/cm2. ► Efficient laser cleaning of the surface oxides in single pulse regime. ► Formation of the periodic surface structures approximately in accordance with the laser wavelength.
