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…
Dephasingless laser wakefield acceleration in a plasma waveguide
J. P. Palastro, K. G. Miller, C. D. Arrowsmith +10
Laser wakefield accelerators (LWFAs) provide extremely large accelerating gradients for compact electron accelerators and photon sources but are limited by dephasing, where trapped…
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…
Generalized multi-dimensional conservation laws for stimulated Raman and Brillouin scattering in a density gradient
Vijay Patel, Sarah Chase, Frank S. Tsung +3
Generalized local and multi-dimensional conservation laws of action, energy, momentum, and angular momentum are derived for stimulated Raman (SRS) and Brillouin backscattering (SBS…
Arbitrary-Velocity Volkov Wavepackets
D. Ramsey, J. McKeown, J. P. Palastro
The evolution of a charged lepton in the field of an electromagnetic plane wave can be described as a superposition of Volkov states. Here we demonstrate that imposing specific mom…
Differentiable Programming for Plasma Physics: From Diagnostics to Discovery and Design
A. S. Joglekar, A. G. R. Thomas, A. L. Milder +3
Differentiable programming, enabled by automatic differentiation (AD), provides a robust framework for gradient-based optimization in computational plasma physics. While optimizati…
