..., where the diameters of the holes are in the range of 20 – 1000 μ m . Microfeatures are also machined and the flexibility of ps laser machining is demonstrated. The quality of drilled holes, e.g., recast layer, microcrack, and conicity, and that of the microstructures, are investigated by an optical...

..., and decohesion zone (see Fig. 3 ). The crushed material grains in the shattered zone form a discontinuous chip. The fracture zone is characterized by material with microcracks linked together but not removed with a chip. The decohesion zone is characterized by separation of graphite flakes or nodules from...
