“…This has become known as the Lawson-Woodward ͑LW͒ theorem. [2][3][4][5][6][7][8] The LW theorem assumes 2,3 ͑i͒ the region of interaction is infinite, ͑ii͒ the laser fields are in vacuum with no walls or boundaries present, ͑iii͒ the electron is highly relativistic (vӍc) along the acceleration path, ͑iv͒ no static electric or magnetic fields are present, and ͑v͒ nonlinear effects ͑e.g., ponderomotive, vϫB, and radiation reaction forces͒ are neglected. One or more of the assumptions of LW theorem must be violated in order to achieve a nonzero net energy gain.…”

Laser driven electron acceleration in vacuum, gases, and plasmas

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.

“…[5][6][7][8] By properly choosing the electron injection point, net acceleration is possible. Consider a radiallypolarized higher-order Gaussian mode propagating along the z axis in the positive z direction, after having been reflected off a mirror located at some negative z position, as shown in Fig.…”

“…The basic idea of the application of the axial electric field of a focused laser beam to accelerate electrons was proposed by Scully et al (Bochove et al 1992;Scully and Zubairy 1991), i.e., when a high-power laser beam is focused, according the Maxwell equations it develops a longitudinal component large enough, which can be used to accelerate electrons along the axis in vacuum, if the electrons are injected with a high enough initial energy. Thus, the difficulties associated with the plasma can be avoided.…”

The acceleration of electrons by using a Bessel-Gaussian (BG) beam in vacuum is studied. It is shown that the axial electric field of a linearly or circularly polarized BG beam of order n = 1 can be used to accelerate electrons. The general features of the acceleration of electrons by using a linearly or circularly polarized BG beam, such as the transversal and axial electric-field components, phase velocity, slippage distance, accelerating potential, and energy gain etc., are analyzed.

“…The simplest such laser accelerator configuration, proposed by Pantell and Piestrup [6], is a single laser beam oriented at a shallow angle to the electron beam and terminated by a downstream boundary. This initial conceptual geometry was followed by the proposal of more refined arrangements employing crossed Gaussian beam configurations [7] and eventually conceptual staged-interaction laser accelerator structures that could in principle sustain very large continuous gradients [8][9][10][11].…”

We recently achieved the first experimental observation of laser-driven particle acceleration of relativistic electrons from a single Gaussian near-infrared laser beam in a semi-infinite vacuum. This article presents an in-depth account of key aspects of the experiment. An analysis of the transverse and longitudinal forces acting on the electron beam is included. A comparison of the observed data to the acceleration viewed as an inverse transition radiation process is presented. This is followed by a detailed description of the components of the experiment and a discussion of future measurements.
