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…
Flying focus with arbitrary directionality for spatiotemporal control of laser pulses
Sida Cao, Devdigvijay Singh, Lavonne S. Mack +2
Flying focus techniques produce laser pulses whose focal points travel at arbitrary, controllable velocities. While this flexibility can enhance a broad range of laser-based applic…
A Reduced Action Integral for Photon-Photon Interactions in Vacuum
D. Ramsey, M. S. Formanek, J. P. Palastro
Electromagnetic waves propagating through vacuum can polarize virtual electron-positron pairs; this polarization, in turn, nonlinearly modifies their propagation. A semi-classical…
Universal structure of propagation-invariant optical pulses
Rafael Russo Almeida, Dillon Ramsey, Ayman F. Abouraddy +2
Space-time structuring of light - where spatial and temporal degrees of freedom are deliberately coupled and controlled - is an emerging area of optics that enables novel configura…
