Energy exchange between free electrons and light in vacuum

Abstract

Energy exchange between heterostructure layers by realspace electron transfer Approximate exchange energy as a functional of the electron density. Light atoms Momentum is exchanged between free electrons and light when the interaction length is limited. An analysis and a computer simulation determine the characteristics of this energy transfer. Possible experimental schemes at optical and infrared wavelengths are explored.

Analysis of Laser Acceleration in a Semi-infinite Space as Inverse Transition Radiation

“…Examples include crossed gaussian laser beams [3], Hermite-gaussian laser beams [4], and other arbitrary laser beam or light diffraction electric field profiles [5]. In addition to semi-open free space laser accelerators other schemes like Inverse-Cerenkov accelerators [6] and guided-wave accelerators [7] (optical or RF) also employ the path integral method of Equation 1 to estimate the electron beam energy gain.…”

LEAP Phase II, Net Energy Gain From Laser Fields In Vacuum

“…This indicates great promise for the production of intense electric fields and for high gradient acceleration. Many schemes for using these large fields directly in a dielectric structure have been proposed [1,2]. STELLA and STELLA-II at Brookhaven have also demonstrated acceleration of electrons using Inverse Free Electron Lasers [3].…”

Analysis of Laser-Driven Particle Acceleration fromPlanar Infinite Conductive Boundaries

“…Historically the energy gain calculations for laser-driven particle acceleration in semiopen structures typically utilized the field Path Integral Method (PIM) of the incident laser field co-propagating with the electron beam and made no assumptions about the accelerator structure other than its ability to 'magically' terminate the laser field [4,5]. At first glance this raises the question to the general validity of the path integral energy gain method and would prompt us to seek special instances where we would expect ITR and PIM have different energy gain predictions.…”
