Title: Observations on Microbunching of Electrons in Laser-Driven Plasma Accelerators and Free-Electron Lasers

Abstract

The periodic longitudinal density modulation of relativistic electrons at the resonant wavelength ( is a fundamental aspect of free-electron lasers ( FELs).In one case, microbunching fractions reached 20% at saturation of a self-amplified spontaneous emission ( FEL resulting in gains of 1 million at 530 nm .In that experiment the z-dependent gain of coherent optical transition radiation ( was also measured In laser-driven plasma accelerators ( microbunching at visible wavelengths has also been recently reported as evidenced by significant COTR enhancements measured in near-field and far-field images on a single shot for the first time.An analytical model for COTR interferometry ( addresses both cases.The broadband microbunching observed in the LPA case could act as a seed for a SASE FEL experiment with tunability in principle over the visible regime.
