Enhancement Cavities For The Generation Of Extreme Ultraviolet And Hard X-Ray Radiation Summary And Outlook

Enhancement cavities are a mature technology with various applications ranging from spectroscopy to the generation of hard x-ray radiation. The enhancement of laser pulses to ultra high average powers is beneficial for all light-matter interactions with small cross-section, either for spectroscopy (detection) or for frequency conversion (generation). The results from this thesis have implications in particular for two of them, namely inverse-Compton scattering and cavity-enhanced high-harmonic generation. In the following, these results are summarised and further possible improvements are discussed in this respect.
