In this paper, a free-electron laser (FEL) growth rate with a laser wiggler in which plasma background is used to generate short wavelengths in x-ray regimes, has been investigated theoretically. A linearly polarized laser pulse, due to having short wiggler periods (inrange) is able to produce coherent radiations in x-ray regions and can be applied as a planar wiggler in a FEL. Phase velocity o...
One of the interesting Laser-Plasma phenomena, when the laser power is high and ultra intense, is the generation of large amplitude plasma waves (Wakefield) and electron acceleration. An intense electromagnetic laser pulse can create plasma oscillations through the action of the nonlinear pondermotive force. electrons trapped in the wake can be accelerated to high energies, more than 1 TW. Of t...
In experimental studies of laser-plasma interactions, the laser radiation can exist inside plasma regions where electron density is below critical (“underdense” plasma), as well at surface density. The could exhibit a rich physics. Namely, incident get converted in transverse electromagnetic waves significantly higher amplitudes than radiation, due to various nonlinear processes. We proposed di...
