In recent years, echo-enabled harmonic generation (EEHG) demonstrated that it is capable to upshift the seed frequency in an FEL by almost two orders of magnitude. In this presentation, I will talk about the EEHG concept in FELs and show its connection to the echo effect known in other areas of physics (such as spin echo, plasma echo, echo in accelerators, etc.). The physics of the EEHG will...

The use of external lasers to initiate the FEL process has been introduced as a way to prepare the electron beam before entering the FEL radiator and to allow the generation of radiation pulses with increased brightness in shorter undulator. Over the recent years, new methods have been proposed and implemented to extend the capabilities of external seeding toward shorter wavelengths.

One of the fundamental facets of microbunching in relativistic electron beams is the potential for generation of coherent radiation at the wavelengths that characterize that periodic longitudinal modulation. This microbunching is an inherent process in the free-electron laser (FEL) mechanism for both single-pass and oscillator configurations. Besides the FEL output, diagnostics of these...

Novel acceleration and FEL concepts
Invited Orals

Laser manipulation of electron beams is important for controlling free-electron lasers. In this talk, I will discuss how strong seeding can enable powerful, efficient FELs and high gradient acceleration when paired with strong tapering. I will then show how laser driven optical compression led to attosecond X-ray FEL pulses at LCLS and plans to use lasers to generate high repetition rate...

Laser assisted beam manipulation has been extensively used in modern high gain FELs to tailor the output properties. In this talk, I will focus on several advanced techniques on high harmonic generation and ultrashort pulse generation with assistant of external UV or IR lasers. With the help of state-of-the-art laser technologies, it’s very likely these techniques will open new opportunities...
