Abstract

The quality of laser machined surface and bulk of different materials with applications in micro-technologies is investigated. Machining occurred with a 248 nm KrF excimer laser and a particularly designed optical system. Optimising tests were performed on poly methyl methacrylate (PMMA), which were further applied to poly-ethylene terephthalate (PET), silicon and ferromagnetic material. All the tests were performed in normal atmospheric condition. The experimental results are presented and compared for improving the machining quality of materials..
