AB  - Modification of single and complex nickel-palladium samples by laser processing in the femtosecond time domain was studied. The samples were processed by focused Ti:Sapphire laser beam (Clark CPA-2101) with 775 nm laser wavelength, 2 kHz repetition rate, 200 fs pulse duration. The laser-induced morphological modifications have shown dependence on the applied fluences and number of laser pulses. The formed surface nanostructures on the single NiPd/Si and multilayer 5x(Ni/Pd)/Si systems are compared with individual Ni and Pd thin films. The results show an increase in surface roughness, formation of parallel periodic surface structures, appearance of hydrodynamic features and ablation of surface material. At low number of pulses (less than 10 pulses) and low pulse energies range (not over 1.7 mu J), the two types of laser-induced periodic surface structure (LIPSS) can be observed: low and high spatial frequency LIPSS (HSFL and LSFL). For all samples, the measured LSFL periods were 720 nm for the ripples created solely on thin film surfaces during the single pulse action. In the case of the multi-pulse irradiation, the periodicities of created LSFLs on the all investigated thin films have shown tendency to reduction with increasing of pulse energies.

Patterning the materials surfaces was done by a Ti: sapphire system at 775 nm wavelength and 200 fs pulse duration, while varying the output pulse energies and the scanning speed. The formation of laser-induced periodical surface structures were found for both materials.

AB  - For material processing one of the main advantages of using ultra short laser pulses, comparing to long pulses, is the highly localized modification. Ultra short pulse laser modification of materials is valuable for their application in nanotechnology, tribology, microelectronics, medical application, etc. In this paper, special attention is paid to experimental investigations of femtosecond laser surface modification of hard protective coating. The sample has been processed by a Ti:sapphire laser with pulse duration of 200 fs and wavelength of 775 nm. Single and multi pulse irradiation were performed in air. Various analytical techniques were used for characterization. The damage threshold for the examined coating, irradiated by 200 fs pulses, was determined.

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  - We studied surface modification of a double layer protective coating on steel induced by single fs laser pulse irradiation in ambient air. The outer alumina (Al2O3) layer, which protects against aggressive environments, was 1.7 mu m thick and the titanium aluminum nitride (TiAlN) layer in contact with the steel surface had a thickness of 1.9 mu m. The pulses (lambda=775 nm, tau=200 fs) were generated by a Ti:sapphire laser source. The pulse energy was varied from 0.32 mu J to 50 mu J, corresponding to an incident laser fluence of 0.11 J cm(-2) to 16.47 J cm(-2). The surface damage threshold was found to be 0.20 J cm(-2) and the alumina layer removal was initiated at 0.56 J cm(-2). This selective ablation of alumina was possible in a wide range of fluences, up to the maximum applied, without ablating the TiAlN layer beneath. (C) 2012 Elsevier B.V. All rights reserved.

AB  - A target of multilayered TiAlN/TiN coating deposited on steel was irradiated by 200 fs pulses of a Ti:Sapphire laser, operating at 775 nm. Laser fluences of 1.16 J cm(-2) to 116 J cm(-2) produced a range of modifications, from well defined parallel surface structures on the coating, to deep craters in the substrate. Parameters for coating ablation were determined in terms of laser fluence and pulse count. A single-pulse damage threshold was found to be 0.66 J cm(-2) and the damage incubation factor 0.642. At lower laser fluences formation of laser induced parallel surface structures was evident, beginning from the first pulse, with a periodicity of about 580 nm. These structures remained and were pronounced at the rim of the damage spot even when the coating was completely ablated in the centre. (C) 2011 Elsevier B.V. All rights reserved.
