Advancements in Cavity-Based X-ray Laser Technology

Researchers at SLAC National Accelerator Laboratory have made significant progress in the development of cavity-based X-ray free-electron laser technology. They used high-quality synthetic diamond mirrors to steer X-ray laser pulses around a rectangular racetrack inside a vacuum chamber. This approach aims to make X-ray laser pulses brighter and cleaner, similar to regular laser beams. The successful delivery of a cavity-based X-ray free-electron laser will revolutionize X-ray science by providing a significant improvement in beam performance. The research team is already working on the next version of the experimental cavity system in collaboration with Argonne National Laboratory.
