abstract
In this work, the use of an innovative, compact femtosecond laser operating in the GHz regime for laser ablation and microtexturing is investigated and discussed. The processing performances of burst mode for pulses shot in the GHz regime are
numerically simulated. The proposed ablation model is based on the two-temperature model and considers, in a simplified way, the effect of plasma. The numerical results are compared in terms of ablation depth with experimental investigations on stainless steels. The numerical outputs allow an understanding of the influence of different process parameters and support the selection of the operating window where GHz laser became competitive with traditional ultrashort laser sources in the MHz regime.

abstract
Biomedical implants interact with human tissues introducing significant perturbation into the body. Implant surfaces can be then functionalized enabling better biocompatibility. At the same time, the additional use of a coating provides further functions such as corrosion protection, osteointegration, and drug delivery. In this context, a composite made of chitosan and bioactive glass nanoparticles has been used for coating Ti6Al4V alloy samples processed beforehand using different processes, i.e., polishing, milling, grit blasting, and electrical discharge machining. Experiments have been carried out to correlate substrate surface conditions and coating effectiveness in terms of scratch resistance with the final aim to obtain suitable guidelines to improve substrate-coating performances.
