TLDR
In this paper, an inverse Cherenkov laser acceleration configuration is presented in which a laser beam is self-guided in a partially ionized gas, and the stability of self-guiding beams is analyzed and discussed.Abstract:
In this paper we discuss some of the important issues pertaining to laser acceleration in vacuum, neutral gases, and plasmas. The limitations of laser vacuum acceleration as they relate to electron slippage, laser diffraction, material damage, and electron aperture effects, are discussed. An inverse Cherenkov laser acceleration configuration is presented in which a laser beam is self‐guided in a partially ionized gas. Optical self‐guiding is the result of a balance between the nonlinear self‐focusing properties of neutral gases and the diffraction effects of ionization. The stability of self‐guided beams is analyzed and discussed. In addition, aspects of the laser wakefield accelerator are presented and laser‐driven accelerator experiments are briefly discussed.read more

E. Esarey,Phillip Sprangle +1 more
TL;DR: The nonlinear interaction of ultraintense laser pulses with electron beams and plasmas is rich in a wide variety of new phenomena as discussed by the authors, including laser excitation of large-amplitude plasma waves (wake fields), relativistic optical guiding of laser pulses in preformed plasma channels, laser frequency amplification by ionization fronts and plasma waves, and stimulated backscattering from plasma and electron beams, and cooling of electron beams by intense lasers.

Vacuum electron acceleration by an intense laser
TL;DR: In this paper, the characteristics and essential conditions under which an electron, in a vacuum laser beam, can undergo a capture and acceleration scenario (CAS) were investigated. But the experimental results were limited to the case where the electron was trapped in the acceleration phase of the wave for a longer time.
