Ultrafast Pulse Retrieval from Partial FROG Traces Using Implicit Diffusion Models
Abhimanyu Borthakur, Jack Eden Hirschman, Sergio Carbajo
Ultrashort laser pulses enable attosecond-scale measurements and drive breakthroughs across science and technology, but their routine use hinges on reliable pulse characterization.…
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…
Structured Light at the Extreme: Harnessing Spatiotemporal Control for High-Field Laser-Matter Interactions
Sergio Carbajo, Seung-Whan Bahk, Justin Baker +19
This review charts the emerging paradigm of intelligent structured light for high-field laser-matter interactions, where the precise spatiotemporal and vectorial control of light i…
Deep Learning Assisted Modeling for Nonlinear Optics
Jack Hirschman, Erfan Abedi, Minyang Wang +6
