Pulsed laser radiation is a powerful tool for micro machining of different materials. The laser beam can be focused to spot diameters in the micron range. Depending on the material properties (e.g. heat conductivity), the thermal influence can be limited by using different pulse duration between nanoseconds (10–9 s) and femtoseconds (10–15 s).
