Advanced Control of Electron Beams: Tailoring X-ray Production with Programmable Laser Shaping
Jack Hirschman, Randy Lemons, Hao Zhang +23
Leveraging the full scientific capabilities of next-generation high-repetition-rate free-electron lasers requires programmable control over electron-beam properties at their source…
Physics-Guided Inverse Design of Optical Waveforms for Nonlinear Electromagnetic Dynamics
Hao Zhang, Jack Hirschman, Randy Lemons +7
Structured optical waveforms are emerging as powerful control fields for the next generation of complex photonic and electromagnetic systems, where the temporal structure of light…
Upstream Laser-based Longitudinal Enhancement of Relativistic Photoelectrons
Hao Zhang, Randy Lemons, Jack Hirschman +23
Controlling the longitudinal phase space of high-brightness relativistic electron beams is crucial for advancing a broad spectrum of charged-particle-based instrumentation and scie…
Deep Learning Assisted Modeling for Nonlinear Optics
Jack Hirschman, Erfan Abedi, Minyang Wang +6
Modeling second-order () nonlinear optical processes remains computationally expensive due to the need to resolve fast field oscillations and simulate wave propagation us…
Nonlinear Shaping in the Picosecond Gap
Randy Lemons, Jack Hirschman, Hao Zhang +2
Lightwave pulse shaping in the picosecond regime has remained unaddressed because it resides beyond the limits of state-of-the-art techniques, either due to its inherently narrow s…
