Scaling of laser effects
Efficient high-energy lasers have been established tools in industry, research and development for a long time. In addition to their application for material processing and additive manufacturing, Fraunhofer EMI is also examining novel applications in the fields of security and defense research. These research activities take advantage of the laser’s property to transmit energy in form of a highly directed beam even over long distances.
Whereas many techniques of material processing are carried out with a laser power in the order of a few kilowatts, there are also high-performance systems with a laser power of more than 100 kilowatts commercially available. In order to be able to assess the potential of such laser systems, EMI carries out studies regarding the scaling properties of high-power laser effects. For this purpose, experimental as well as numerical and analytical approaches are used, which investigate for example non-linear effects occurring in the interaction of intense laser beams with matter. These studies allow the classification of the potential of the next generation of laser systems for future applications.
