Experimental demonstration of Flying-Focus enhanced Thomson scattering
E. Gerstmayr, C. Mariani, R. Fitzgarrald +23
We report the experimental demonstration of a spatiotemporally engineered "Flying-Focus" laser pulse for enhanced x-ray generation in relativistic Thomson scattering. A combination…
Scaling Interferometry to the Multi-Petawatt Regime
Mara L. Klebonas, Hernan J. Quevedo, Calin I. Hojbota +6
Pre-plasma conditions strongly influence laser-plasma interactions in the multi-petawatt (MPW) regime, increasing the need for reliable early-time plasma evolution diagnostics. Amo…
Ion-motion-driven enhancement of energy coupling and stability in relativistic laser-microchannel interaction
K. Weichman, M. VanDusen-Gross, G. Bruhaug +5
For sufficiently short relativistic-intensity laser pulses, the disparity in time scales for electron and ion motion causes ions to behave as a fixed, neutralizing background. As t…
Testing strong-field QED with the avalanche precursor
A. A. Mironov, S. S. Bulanov, A. Di Piazza +8
A two-beam high-power laser facility is essential for the study of one of the most captivating phenomena predicted by strong-field quantum electrodynamics (QED) and yet unobserved…
On Measuring Stimulated Photon-photon Scattering using Multiple Ultraintense Lasers
Hans G. Rinderknecht, E. Dill, A. J. MacLeod +8
Stimulated photon-photon scattering is a predicted consequence of quantum electrodynamics that has yet to be measured directly. Measuring the cross-section for stimulated photon-ph…
Joule-Class Pulsed THz Sources from Microchannel Targets
G. Bruhaug, H. G. Rinderknecht, K. Weichman +9
Inference of joule-class THz radiation sources from microchannel targets driven with hundreds of joule, picosecond lasers is reported. THz sources of this magnitude are useful for…
