Laser Electron Accelerator
Toshiki Tajima,John M. Dawson +1 more
TL;DR: In this paper, an intense electromagnetic pulse can create a weak of plasma oscillations through the action of the nonlinear ponderomotive force, and electrons trapped in the wake can be accelerated to high energy.

Radiation from Cerenkov Wakes in a Magnetized Plasma
TL;DR: In this paper, the Cerenkov wake excited by a particle beam or a short laser pulse in a perpendicularly magnetized plasma is analyzed, and the wake couples to electromagnetic radiation of approximate frequency {omega}{sub c}/{omega} times the amplitude of the wake excited in the plasma (for a sharp boundary).

Terahertz generation via optical rectification of x-mode laser in a rippled density magnetized plasma
Lalita Bhasin,V. K. Tripathi +1 more
TL;DR: In this article, a scheme of terahertz radiation generation by the optical rectification of a picosecond laser pulse in rippled density magnetized plasma is examined, where the x-mode laser pulse, propagating perpendicular to dc magnetic field, exerts a quasistatic ponderomotive force on electrons, imparting them a drift with finite transverse component.

Strong terahertz radiation generation by beating of extra-ordinary mode lasers in a rippled density magnetized plasma
TL;DR: In this paper, a terahertz radiation generation scheme was proposed by beating of two extra-ordinary lasers having frequencies and wave numbers and wave number with a wave number mismatch factor q which is introduced by the periodicity of plasma density ripples.

Excitation of electromagnetic wake fields in a magnetized plasma
Gert Brodin,Jonas Lundberg +1 more
TL;DR: In this article, a self-consistent system of equations describing wake-field generation in the weakly nonlinear limit is derived for short electromagnetic pulses in a magnetized plasma.
