Description
Diffractive optics have interesting properties that make them highly attractive for use with X-ray and EUV radiation. In contrast to other kinds of x-ray optics such as mirrors and lenses, diffractive optics allow for precise control of the optical wave front and the realization of complex optical functionalities. Applications range from time dispersive elements for single-shot demagnetization experiments to beam splitting in time-resolved X-ray absorption spectroscopy and 4-wave mixing experiments. The presentation covers aspects of the design and fabrication of diffractive optical elements for FEL radiation and presents examples of resulting experiments in ultra-fast science.
