AB  - We studied surface modification of a bi-layered coating (Al2O3/TiAlN/steel)
induced by fs laser with single and multi-pulse irradiation. The laser pulses
(λ=775 nm, τ=200 fs) were generated by a Ti:sapphire laser. The single pulse
threshold fluence for ablation of the top Al2O3 layer was Dath =0.56 Jcm-2. Single
pulse actions with fluence increased up to 16.47 Jcm-2 caused widening of ablated
area without significant change of the TiAlN layer underneath. In case of multipulse irradiation, periodical surface structures (LIPSS) were induced on the TiAlN
layer surface. The average periodicity of created LIPSS was 600 nm.

AB  - The interaction of a pulsed TEA CO2 laser with nickel thin film, deposited on single crystalline silicon substrate, was studied. The results have shown that the high reflectivity nickel thin film was modified and partially removed if the laser energy density was 23 J/cm2. Experiment was conducted in multipulse laser irradiation regime. Modifications of thin nickel film in function of successive laser pulses, at constant pulse energy, can be summarized as: (i) thin film roughness and microcracking, (ii) partially exfoliation, (iii) locally substrate modification, and (iv) plasma appearance.
