The development of next generation (compact) light sources, X-ray Free-Electron Lasers (XFELs) driven by compact electron accelerators and using short period undulators, is extremely challenging. To understand their complex physical behavior, the analysis of experimental data, identification of theories based on mathematical concepts and usage of advanced discretization techniques with optimal performance properties are indispensable. Combining the algorithms with machine learning offers the potential to accelerate simulations, such that a real breakthrough becomes feasible, by inferring knowledge from data bases instead of computing all physical quantities on fine scales. This concept is implemented for optimization of Terahertz (THz) generation in periodically poled Lithium Niobate (PPNL).
