X-ray free-electron lasers (x-ray FELs) give us for the first time the possibility to explore
structures and dynamical processes of atomic and molecular systems at the angstrom …

High-gain free-electron lasers (FELs) are being developed as extremely bright sources for a
next-generation x-ray facility. In this paper, we review the basic theory of the start-up, the …

Plasma waves excited by intense laser beams can be harnessed to produce femtosecond
duration bunches of electrons with relativistic energies. The very large electrostatic forces of …

Development of coherent radiation sources for a wavelength ‚below 1 angstrom (ie, in the
hard X-ray and gamma ray ranges) is a challenging goal of modern physics. Sub-angstrom …

We investigate the quantum regime of a high-gain free-electron laser starting from noise. In
the first part, we neglect the radiation propagation and we formulate a quantum linear theory …

The quantum regime of the free-electron laser (FEL) emerges when the discreteness of the
momentum of the electron plays a dominant role in the interaction with the laser and the …

Starting from the eikonal approximation (geometrical optics), a set of nonlinear quantum
plasma fluid equations to describe the quantum free-electron laser (FEL) is presented …

The interaction between high-brilliance electron beams and counterpropagating laser
pulses produces x rays via Thomson backscattering. If the laser source is long and intense …

A free-electron laser (FEL) operating in the quantum regime can provide a compact and
monochromatic x-ray source. Here we present the complete quantum model for a FEL with a …
