abstract = "Interaction of a TEA CO2laser, operating at 10.6 μm wavelength and pulse length of 100 ns, with titanium target (implant), in nitrogen and carbon-dioxide gas ambience was studied. The Ti-surface modifications were studied at moderate fluence (~17J/cm2) and intensity (~60MW/cm2) regime.The energy absorbed from the laser beam was partially convertedto thermal energy, which generated a series of effects, such as melting, vaporization of the molten material, shock waves, etc. The following Ti-surface changes and phenomena were observed: (i) superficial damages in both atmospheres; (ii) creation of cone-and hill-like structures in atmosphere of N2and CO2, respectively; (iii) possible formation of TiN, Ti-oxide(s) and, Ti-carbide layers, in N2and CO2gas, respectively and, (iv) occurrence of plasma inboth gas ambiences. It can be concluded that the applied laser fluence was high enough to produce effective modification of the Ti-implant target in nitrogen as well as in carbon-dioxide gas. Creation of plasma may provide sterilization effect.",
