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…
Electromagnetic Solitons in Quantum Vacuum
S. V. Bulanov, P. V. Sasorov, F. Pegoraro +5
In the limit of extremely intense electromagnetic fields the Maxwell equations are modified due to the photon-photon scattering that makes the vacuum refraction index depend on the…
Multiple-colliding laser pulses as a basis for studying high-field high-energy physics
J. Magnusson, A. Gonoskov, M. Marklund +10
Apart from maximizing the strength of optical electromagnetic fields achievable at high-intensity laser facilities, the collision of several phase-matched laser pulses has been the…
Similarity of magnetized plasma wake channels behind relativistic laser pulses with different wavelengths
Andreas Bierwage, Timur Zh. Esirkepov, James K. Koga +1
Using particle-in-cell simulations of relativistic laser plasma wakes in the presence of an external magnetic field, we demonstrate that there exists a parameter window where the d…
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…
Boosted High Order Harmonics from Electron Density Singularity Formed at the Relativistic Laser Bow Wave
Jie Mu, Timur Zh. Esirkepov, Yanjun Gu +7
We demonstrate coherent hard electromagnetic radiation generation from reflection by the electron density singularity formed at the relativistic bow wave in laser plasma via partic…
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…
