Recoil Effects on Reflection from Relativistic Mirrors in Laser Plasmas
P. Valenta, T. Zh. Esirkepov, J. K. Koga +10
Relativistic mirrors can be realized with strongly nonlinear Langmuir waves excited by intense laser pulses in underdense plasma. On reflection from the relativistic mirror the inc…
Enhanced photon emission from a double-layer target at moderate laser intensities
M. Jirka, O. Klimo, Y. J. Gu +1
In this paper we study photon emission in the interaction of the laser beam with an under-dense target and the attached reflecting plasma mirror. Photons are emitted due to the inv…
Absorption and opacity threshold for a thin foil in a strong circularly polarized laser field
Evgeny Gelfer, Alexander Fedotov, Ondrej Klimo +1
We show that a commonly accepted transparency threshold for a thin foil in a strong circularly polarized normally incident laser pulse needs a refinement. We present a new analytic…
Wakefield Excited by Ultrashort Laser Pulses in Near-Critical Density Plasmas
Petr Valenta, Ondrej Klimo, Gabriele M. Grittani +3
Laser wakefield acceleration (LWFA) using high repetition rate mJ-class laser systems brings unique opportunities for a broad range of applications. In order to meet the conditions…
Feasibility of optical probing of relativistic plasma singularities
Timur Zh. Esirkepov, Jie Mu, Yanjun Gu +9
Singularities in multi-stream flows of relativistic plasmas can efficiently produce coherent high-frequency radiation, as exemplified in the concepts of Relativistic Flying Mirror…
