    For drilling holes such as cooling holes in turbine blades with diameters from 100 µm up to 1.5 mm flash lamp pumped laser sources e.g. slab lasers are commonly used. These laser sources have peak powers of several kW at pulse durations from microseconds up to milliseconds with a high beam quality. Due to the beam quality, small spot...

    To drill sub-millimeters holes one of the way is laser drilling. Laser drilling is a well-established industrial process from decades; however several fundamental questions are still unsolved about the physical understanding of the laser matter interaction. A sequential description of the laser drilling process can be made as following. The irradiated surface is heated by absorption of laser energy. Once the surf...

    Laser cutting and drilling for concrete are an attractive method for dismantling nuclear facilities and performing reconstruction generally of public buildings. The reduced amount of secondary waste is ideal for cutting irradiated biological shield walls in nuclear power plants, and the decre...

    Presented at ICALEO 2011

    Now, nearly a decade since the introduction of the high brilliance solid state lasers, an evolution of industrial high power laser materials processing is ongoing. In this paper will be focused on the largest market for high power lasers: metal laser cutting. The state-of-the-art of laser cutting with fibre- and disc-lasers will be compared to the benchmarking laser for metal cutting: The CO2-laser. The opportunities and challenges for the new laser sources in conquering this market will be discussed. Both classical cutting with gas assistance as well a...

    The remote cutting technique provides an enormous potential in terms of cutting speeds when working on thin sheets. Even in contour cutting speeds about 100 m/min are realizable [1]. Working without any cutting gas the material of the cutting kerf must be vaporized partially. It is evident...

    Presented at ICALEO 2011

    We have investigated striation generation process during laser cutting of steel with inert gas. Our experimental analysis of hydrodynamics of melt layer on kerf front has brought new insights into the mechanisms of this process, which have been left unknown for a long time in spite of the significance for industrial applications. The results have shown that the melt flow can split into two flows that can be independent, one being located along the cent...
