Abstract (EN): This work focus the potential of the ns pulsed Nd: YAG (1064 nm) fiber Laser for the microtexturing of Ti and its alloys, targeting its application for dental implants surfaces. The influence of Laser process parameters, such as pulse width and pulse overlap, on the surface morphology characteristics of TiCP GII and Ti-6Al-4V is analyzed, and its impact to the surface wettability is discussed. The results show that combining different levels of pulse width (10-200 ns), peak power (<10 kW) and pulse overlap (0-90%), three types of surfaces can be created, namely, patterned, isotropic and/or oxidized surfaces, with distinct functional properties. Slight morphological differences observed between TiCP and Ti-6Al-4V and the stronger oxidation in TiCP were seen to have a significant impact on the wetting behavior of these surfaces. Ti-6Al-4V textured with 200 ns pulses presented the lowest contact angles, independently of the pulse overlap rate.
