AB  - Free Electron Lasers produce X-ray light with almost perfect coherence. The optical elements of the beam transport system have to fulfill therefore much more stringent - and in part also different - specifications compared to similar optics at synchrotron radiation sources. Another aspect of X-ray laser light is that it is generated in very intense and short pulses, which leads to the effect that the heat pile-up in anything intercepting the beam and can outrun the thermal transport on different time scales. This poses strong limitations on the suitable materials that can be used for mirror coatings, slits, attenuators and absorbers. Under certain conditions the beam can drill very fast through thick slabs of material, which opens up new possibilities for technical applications but poses also new challenges to the radiation safety system. This tutorial gives an overview of the basic relations needed to understand the physics of X-ray optics at free electron lasers and illustrates also experiences from the first two years of operation of the European XFEL.
