Gamma-Ray Flash Generation in Irradiating Thin Foil Target by Single Cycle Tightly Focused Extreme Power Laser Pulse
Prokopis Hadjisolomou, Tae Moon Jeong, Petr Valenta +2
We present a regime where an ultra-intense laser pulse interacting with a foil target results in high -photon conversion efficiency, obtained via three-dimensional quantum-elect…
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…
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…
