Material surface modification by ns, ps and fs laser pulses
The laser surface modifications of a bulk material Inconel 600 and a multilayered titanium-
aluminium-nitride/titanium-nitride (TiAlN/TiN) coating are of great interest for fundamental
and practical aspects. Observation of surface changes of the Inconel 600 and TiAlN/TiN
induced by ultra-short (fs and ps) and short (ns) lasers is considered. It is shown that all laser
systems can stimulate morphological changes at the target surface, and the irradiation with
ultra-short pulses results in a better definition of the damage. Fs laser pulses can produce a …
