Electron trapping and field propagation in laser-plasma interaction with density transition
This paper investigates that by using a new electron density transition in plasma, the wave breaking threshold was reduced and transversely electron injection into the acceleration phase of the wake field was increased. Numerical results identify that injected electron bunch causes to modification of the wake field. By optimization of transient length and injected charge of electron, electromagnetic propagation and electron density variation in plasma has been evaluated and the efficient energy and gain of electrons have been obtained.
