Nonlinear Optics in Relativistic Plasmas and Laser Wake Field Acceleration of Electrons
TLDR
Electron acceleration and the appearance of high-frequency modulations in the transmitted light spectrum were both found to have sharp thresholds in laser power and plasma density.Abstract:
When a terawatt-peak-power laser beam is focused into a gas jet, an electron plasma wave, driven by forward Raman scattering, is observed to accelerate a naturally collimated beam of electrons to relativistic energies (up to 10 9 total electrons, with an energy distribution maximizing at 2 megaelectron volts, a transverse emittance as low as 1 millimeter-milliradian, and a field gradient of up to 2 gigaelectron volts per centimeter). Electron acceleration and the appearance of high-frequency modulations in the transmitted light spectrum were both found to have sharp thresholds in laser power and plasma density. A hole in the center of the electron beam may indicate that plasma electrons were expelled radially.read more

Optics in the relativistic regime
TL;DR: In this paper, a number of consequences of relativistic-strength optical fields are surveyed, including wakefield generation, a relativistically version of optical rectification, in which longitudinal field effects could be as large as the transverse ones.

TL;DR: An energy gain of more than 42 GeV is achieved in a plasma wakefield accelerator of 85 cm length, driven by a 42GeV electron beam at the Stanford Linear Accelerator Center (SLAC), in excellent agreement with the predictions of three-dimensional particle-in-cell simulations.

Self‐focusing of short intense pulses in plasmas
TL;DR: In this paper, the self-focusing of relativistically intense laser light pulses is analyzed, where the pulse length is short enough that ion inertia prevents any significant motion of ions.
