Enhancement of nonlinear pair production in a flying-focus pulse
Md Reshad Ur Rahman, Martin S. Formanek, Elias Gerstmayr +3
A photon can decay into an electron-positron pair in the presence of an intense laser pulse by a process known as nonlinear Breit-Wheeler pair production (NBWPP). For a sufficientl…
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…
Enhanced quantum radiation with flying-focus laser pulses
Martin S. Formanek, John P. Palastro, Dillon Ramsey +1
The emission of a photon by an electron in an intense laser field is one of the most fundamental processes in electrodynamics and underlies the many applications that utilize high-…
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…
Analytic pulse technique for computational electromagnetics
K. Weichman, K. G. Miller, B. Malaca +6
Numerical modeling of electromagnetic waves is an important tool for understanding the interaction of light and matter, and lies at the core of computational electromagnetics. Trad…
Radiation Reaction Enhancement in Flying Focus Pulses
Martin Formanek, Dillon Ramsey, John P. Palastro +1
Radiation reaction (RR) is the oldest still-unsolved problem in electrodynamics. In addition to conceptual difficulties in its theoretical formulation, the requirement of exceeding…
