Results from analytical studies and computer simulations of the nonlinear evolution of wake waves in inhomogeneous plasmas are presented. It is shown that the wake wave-breaking that appears due to the inhomogeneity of the Langmuir frequency can be used to inject electrons into the acceleration phase of the wave. In the wake wave excited behind a finite-width laser pulse, the wave-breaking mechanism involves the increase in the curvature of the wake front with the distance from the pulse, followed by the self-intersection of the electron trajectories.

Abstract
Results from analytical studies and computer simulations of the nonlinear evolution of wake waves in inhomogeneous plasmas are presented. It is shown that the wake wave-breaking that appears due to the inhomogeneity of the Langmuir frequency can be used to inject electrons into the acceleration phase of the wave. In the wake wave excited behind a finite-width laser pulse, the wave-breaking mechanism involves the increase in the curvature of the wake front with the distance from the pulse, followed by the self-intersection of the electron trajectories.File in questo prodotto:
