Low surface quality of as-deposited laser metal deposition (LMD) parts is one the main drawbacks this additive manufacturing technology that prevents direct use without implementation costly and time consuming post-processes. An in-process finishing operation need auxiliary equipment highly appealing to overcome such issues. For reason, re-melting performed with same used for process a promisin...

Waterjet guided laser processing is an internationally patented technique based on guiding a laser inside a thin, high-speed waterjet. The process combines the advantages of laser processing with those of waterjet cutting and offers promise as a method for processing thin and heat sensitive materials with a high degree of precision. An improved understanding of the complex interaction between l...

Laser-based processing enables a wide variety of device configurations comprising thin films and nanostructures on sensitive, flexible substrates that are not possible with more traditional thermal annealing schemes. In near-field optical probing, only small regions of a sample are illuminated by the laser beam at any given time. Here we report a new technique that couples the optical near-fiel...

Silicon nano-wires were fabricated using thin Silicon on Insulator (SOI) wafers and a combination of anisotropic wet etching by TetraMethyl Ammonium Hydroxide (TMAH) and Local Oxidation of Silicon (LOCOS). These nano-wires were submitted to laser exposure using gas immersion laser doping (GILD). The result was the formation of either periodic nano-structures or silicon balls. Since the process ...

We report on the fabrication of fractal dendrites using laser-induced melting aluminum alloys. target boron carbide (B4C), which is one most effective radiation-absorbing materials characterized by a low coefficient thermal expansion. Due to high fragility B4C crystals, we were able introduce its nanoparticles into stabilization matrix AA385.0. The high-intensity laser field action led formatio...
