Using custom optics for ultrashort-pulse enhancement cavities, it demonstrates for the first time that at the envisaged power levels, the mitigation of thermal effects becomes indispensable even in cavities comprising solely reflective optics. It also studies cavities with large beams, albeit with low misalignment sensitivity, as a way to circumvent intensity-induced mirror damage. Average powers of several hundred kilowatts are demonstrated, which benefit hard x-ray sources based on Thomson scattering. Furthermore, pulses as short as 30 fs were obtained at more than 10 kW of average power and employed for high-harmonic generation with photon energies exceeding 100 eV at 250 MHz repetition rate, paving the way for frequency comb spectroscopy in this spectral region. 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5053 606 $aLasers 606 $aPhotonics 606 $aOptics 606 $aElectrodynamics 606 $aQuantum optics 606 $aOptics, Lasers, Photonics, Optical Devices$3https://scigraph.springernature.com/ontologies/product-market-codes/P31030 606 $aClassical Electrodynamics$3https://scigraph.springernature.com/ontologies/product-market-codes/P21070 606 $aQuantum Optics$3https://scigraph.springernature.com/ontologies/product-market-codes/P24050 615 0$aLasers. 615 0$aPhotonics. 615 0$aOptics. 615 0$aElectrodynamics. 615 0$aQuantum optics. 615 14$aOptics, Lasers, Photonics, Optical Devices. 615 24$aClassical Electrodynamics. 615 24$aQuantum Optics. 676 $a621.36 700 $aCarstens$b Henning$4aut$4http://id.loc.gov/vocabulary/relators/aut$0833988 906 $aBOOK 912 $a9910300546503321 996 $aEnhancement Cavities for the Generation of Extreme Ultraviolet and Hard X-Ray Radiation$91864518 997 $aUNINA
