A free-electron laser (FEL) is a (fourth generation) synchrotron light source producing extremely brilliant and short pulses of synchrotron radiation. An FEL functions and behaves in many ways like a laser, but instead of using stimulated emission from atomic or molecular excitations, it employs relativistic electrons as a gain medium. Synchrotron radiation is generated as a bunch of electrons. The interaction of electrons with strong electromagnetic fields is fundamental driving laser dynamically tunes the photon emission spectrum. This work demonstrates a unique free-electron light source, wherein the electron mean Intense Free-Electron Light Sources Based on Graphene.
This book series addresses a newly emerging interdisciplinary research field, Ultrafast Intense Laser Science, spanning atomic and molecular physics, molecular science, and optical science. Its progress is being stimulated by the recent development of ultrafast laser technologies. We study in detail the strong-field QED process of nonlinear Compton scattering in short intense plane wave laser pulses of circular polarization. Our main focus is placed on how the spectrum of the backscattered laser light depends on the shape and duration of the initial short intense pulse.
The standard method used to create attosecond pulses is based on the interaction of near-infrared laser light with the electrons in atoms of noble gases such as neon or argon. Illustration depicting the method outline by LLE researchers to shape intense laser light in a way that accelerates electrons to record energies in very short distances.

This volume focuses on recent advances in the investigation of the interaction of intense electromagnetic fields with free electrons, a rapidly developing field following the advent of.
We calculate the dynamics and the radiation emitted from free electrons in an ultrashort pulsed laser focus. In a Gaussian focus, at low electron densities for which space charge is negligible, we find that ponderomotive forces limit the effective volume of radiation emission to a region that is much smaller than the focal waist and even significantly smaller than the fundamental wavelength.
Equations related to the motion of a free electron in a laser field are also discussed in the chapter. Select Appendices. About the book. Description. Nonlinear optics is the study of the interaction of intense laser light with matter.

Brown, Lowell S. ; Kibble, T. Abstract. The interaction of an intense coherent photon beam with free electrons is discussed. The photon beam is treated as a classical external electromagnetic field.
The discussion is exact within the approximation of neglecting radiative corrections and the restriction to the case of a plane-wave field or arbitrary spectral composition and polarization by: This is an attempt to present an overview of currently performed experiments that investigate some fundamental aspects of the interaction of electrons with intense electromagnetic fields (laser and microwave).
The electrons are free or in a continuum state of the atom or by: 1. This chapter discusses the interaction of very intense light with free electrons. Thomson showed electron would oscillate in the presence of the electromagnetic wave, it would act as a source of dipole radiation itself, with the consequence that a definite fraction of the incident radiant energy flux would be removed from the electromagnetic wave and scattered into other directions.
Fast electrons are generated in the interaction between intense ultra-short laser pulses and the target. This interaction depends on the laser’s intensity, polarization, incident angle, the scale length of the plasma, and the target material.
Ultra-intense laser sources Since the invention of the pulsed laser, peak power has increased by 12 orders of magnitude. (See figure 1.) In the s free-running laser oscillators were first Q-switched and later mode-locked to provide gigawatts of peak power in picosecond pulses.

Intense laser cluster interactions were known to produce energetic ions and electrons, but now, in a paper published today in Physical Review Letters, researchers have revealed that relatively slow electrons or low-energy electrons are also produced in large quantities.
Simulation of a laser-induced cluster explosion. Recently, however, two powerful new experimental techniques have emerged capable of giving alternative experimental views of the electron. We refer to (1) the confinement of single electrons for long term study, and (2) the interaction of electrons with high intensity laser fields.

Interactions of Ultra‐Intense Laser Light with Matter Generating plasma beat waves with extremely short and intense laser pulses may turn out to be the easiest way to accelerate electrons.
d, The free electrons produce light at the laser frequency (the single peak present). Lakhotia et al. 1 show that the band electrons also emit light at odd multiples (high harmonics) of this.
Atoms interacting with intense laser fields can emit electrons and photons of very high energies. An intuitive and quantitative explanation of these highly nonlinear processes can be found in terms of a generalization of classical Newtonian particle trajectories, the so-called quantum orbits.
Very few quantum orbits are necessary to reproduce the experimental results. Conventional solid-density laser-plasma targets quickly ionize to make a plasma mirror, which largely reflects ultra-intense laser pulses.
This Fresnel reflection at the plane boundary largely wastes our e orts at ultra-intense laser/solid interaction, and limits target heating to nonlinear generation of high-energy electrons which penetrate inward.
