High-order alloharmonics produced by nonperiodic drivers
M. S. Pirozhkova, K. Ogura, A. Sagisaka +18
High-order harmonics are ubiquitous in nature and present in electromagnetic, acoustic, and gravitational waves. They are generated by periodic nonlinear processes or periodic high…
Relativistic-flying laser focus by a laser-produced parabolic plasma mirror
Tae Moon Jeong, Sergei V. Bulanov, Petr Valenta +6
The question of electromagnetic field intensification towards the values typical for strong field Quantum Electrodynamics is of fundamental importance. One of the most promising in…
Gamma Factory Searches for Extremely Weakly-Interacting Particles
Sreemanti Chakraborti, Jonathan L. Feng, James K. Koga +1
The Gamma Factory is a proposal to back-scatter laser photons off a beam of partially-stripped ions at the LHC, producing a beam of MeV to GeV photons with intensitie…
Nanoscale subsurface dynamics of solids upon high-intensity laser irradiation observed by femtosecond grazing-incidence x-ray scattering
Lisa Randolph, Mohammadreza Banjafar, Thomas R. Preston +28
Observing ultrafast laser-induced structural changes in nanoscale systems is essential for understanding the dynamics of intense light-matter interactions. For laser intensities on…
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…
Characterization of ionization injection in gas mixtures irradiated by sub-petawatt class laser pulses
A. Zhidkov, N. Pathak, J. Koga +3
Effects of ionization injection in low and high Z gas mixtures for the laser wake field acceleration of electrons are analyzed with the use of balance equations and particle-in-cel…
