Light by Design for Next-Generation Electron Beams Sources and X-ray Free Electron Lasers

Unifying laser and accelerator physics holds great promise for the development of future particle accelerators, light sources, and other scientific instruments due to increasingly synergistic advances at the cross-section between these two fields. Their combined action has recently ushered in advanced scientific facilities to study the ultrafast dynamics of matter at the atomic level. We will review state-of-the-art optical laser upconversion[1] and conditioning[2,3] technologies and methodologies for future electron beam sources, linear accelerators, and X-ray free-electron lasers, including adaptable generation and conditioning of electron beams at high repetition rates.
