Laser induced Chemical Processes

The fundamentals and applications of laser-matter interactions are studied with particular regard to laser material processing. Special attention is given to laser-induced physical and chemical processes at gas-solid, liquid-solid and solid-solid interfaces. At present, the main interests are the modification and ablation of material surfaces, laser-induced chemical vapour deposition (LCVD) and etching, and the formation of coherent and non-coherent structures.
