Photon acceleration of high-intensity vector vortex beams into the extreme ultraviolet
Kyle G. Miller, Jacob R. Pierce, Fei Li +4
Extreme ultraviolet (XUV) light sources allow for the probing of bound electron dynamics on attosecond scales, interrogation of high-energy-density matter, and access to novel regi…
X-ray free-electron lasing in a flying-focus undulator
D. Ramsey, B. Malaca, T. T. Simpson +5
Laser-driven free-electron lasers (LDFELs) replace magnetostatic undulators with the electromagnetic fields of a laser pulse. Because the undulator period is half the wavelength of…
Radiation by a laser-driven flying-focus electron wave packet
Antonino Di Piazza, Martin Formanek, Dillon Ramsey +1
An exact solution of the Dirac equation in the presence of an arbitrary electromagnetic plane wave is found, which corresponds to a focused electron wave packet, with the focus of…
Dephasingless two-color terahertz generation
Tanner T. Simpson, Jeremy J. Pigeon, Kyle G. Miller +3
A laser pulse composed of a fundamental and an appropriately phased second harmonic can drive a time-dependent current of photoionized electrons that generates broadband THz radiat…
Laser wakefield acceleration of ions with a transverse flying focus
Zheng Gong, Sida Cao, John P. Palastro +1
The extreme electric fields created in high-intensity laser-plasma interactions could generate energetic ions far more compactly than traditional accelerators. Despite this promise…
Superluminal matter waves
J. P. Palastro, D. Ramsey, M. Formanek +2
The Dirac equation has resided among the greatest successes of modern physics since its emergence as the first quantum mechanical theory fully compatible with special relativity. T…
Self-focused pulse propagation is mediated by spatiotemporal optical vortices
M. S. Le, G. A. Hine, A. Goffin +2
We show that the dynamics of high-intensity laser pulses undergoing self-focused propagation in a nonlinear medium can be understood in terms of the topological constraints imposed…
