“…This is the well-known inverse freeelectron laser (I-FEL) [4,22] suggested first by Palmer [59] in 1972. In a similar manner Edighoffer et al [2] suggested to use the inverse condition for Cerenkov radiation to accelerate electrons -inverse Cerenkov acceleration (ICA) [11], and Kroll [60] conceived using the Smith-Purcell effect [61] for the same purpose. Correspondingly, utilizing an active medium for particle acceleration suggests that the PASER mechanism may be conceived as the inverse laser effect.…”

We review the theory and the experimental demonstration of one of the novel advanced particle acceleration techniques dubbed PASER -for particle acceleration by stimulated emission of radiation. In such an acceleration paradigm, bundles of electrons are accelerated using the same principle as in laser. A proof-of-principle experiment, conducted at the Brookhaven National Laboratory, demonstrated this novel acceleration scheme. A 45 MeV electron macrobunch was modulated by a high-power CO2 laser in a wiggler, and then injected into an excited CO2 gas mixture. The emerging microbunches reveal a 0.15% relative change in the kinetic energy in less than 40 cm long interaction region. This is the first experimental demonstration of coherent collisions of the second kind. The fundamental physics underlying the PASER paradigm is discussed via the analysis of a two-dimensional analytic model used to evaluate the energy exchange occurring as a train of electron microbunches traverses an active medium. Furthermore, advanced PASER concepts such as non-linear interaction of electrons and waves in an active medium, the occurrence of resonant absorption instability, and PASER-based optical Bragg accelerators, are considered as well. The possible impact of PASER-based accelerators on future compact medical accelerators, and on high-energy physics applications is discussed.Light-electron-atom interaction.

The charged particles nonlinear dynamics in the field of a strong electromagnetic wave pulse of finite duration and certain form of the envelope, in the refractive medium with a constant and variable refraction indexes, is investigated by means of numerical integration of the classical relativistic equations of motion. The particle energy dependence on the pulse intensity manifests the nonlinear threshold phenomenon of a particle reflection and capture by actual laser pulses in dielectric-gaseous media that takes place for a plane electromagnetic wave in the induced Cherenkov process. Laser acceleration of the particles in the result of the reflection from the pulse envelope and in the capture regime with the variable refraction index along the pulse propagation direction is investigated.

“…So far, many acceleration schemes involving media or use of near-field effects have been put forward, such as plasma acceleration [2], IFEL acceleration [3], and inverse Cerenkov acceleration [4] etc., some of which have shown certain practical feasibility in laboratories [5]. But as for the far-field acceleration in vacuum is concerned, there still exists the long-standing question as to whether or not a charged particle can obtain an energy gain from a laser beam in a vacuum when the interaction length is unlimited [6].…”

By calculation of the classical Newton-Lorentz equation and neglecting the radiation reaction, we find that when an electron is scattered by an intense continuous monochromatic laser beam (' e.*E6 i /S : f in the interaction region), there can be not only momentum transfer but also noticeable energy transfer between the free electrons and the laser beam. This kind of inelastic effect comes from nonlinear Compton scattering. PACS Nos.: 42.50Vk and 42.50 Hz Résumé : Ce papier présente les résultats de l'intégration numérique de l'équation classique de Newton-Lorentz en négligeant la réaction de radiation. Nous trouvons que lorsque l'électron est diffusé par un champ laser monocromatique intense (' e.*E6 i /S : f dans la région d'interaction), il n'y a pas uniquement transfert de moment, mais aussi transfert notable d'énergie entre l'électron et le champ laser. Ce type d'effet inélastique vient de la diffusion non-linéaire de Compton. [Traduit par la rédaction]
