Title Compression of X-ray Free Electron Laser Pulses to Attosecond Duration
Abstract State of the art X-ray Free Electron Laser facilities currently provide the brightest X-ray pulses readily available, typically with mJ energy and several hundred femtosecond duration. Here we present one- and two-dimensional Particle-in-Cell simulations, utilising the process of stimulated Raman amplification, showing that these pulses are compressed to a temporally coherent, subfemtosecond pulse at 8% efficiency. One or more sequential pulses of this type may pave the way for novel attosecond scattering experiments, probing the evolution of bound electron wavefunctions. Furthermore, evidence is presented that significant Landau damping and wavebreaking may be beneficial in distorting the rear of the interaction and further reducing the final pulse duration.
