Learning high-dimensional quantum entanglement through physics-guided neural networks
Yang Xu, Hao Zhang, Wenwen Zhang +4
High-gain spontaneous parametric down-conversion (SPDC) produces bright squeezed vacuum with rich high-dimensional entanglement, but its output is inherently multimodal and non-per…
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.…
A spectral phase modulation transfer function for dispersive four-wave mixing
Linshan Sun, Sergio Carbajo
Indirect control of ultraviolet (UV) pulse phase through nonlinear frequency conversion is attractive when direct UV pulse shaping is limited by material loss, dispersion, and dama…
Programmable spectral phase transfer to the ultraviolet by gas-filled-fibre four-wave mixing
Linshan Sun, Hao Zhang, Cameron Leary +2
Programmable shaping of femtosecond ultraviolet (UV) pulses is still much less flexible than at visible and near-infrared wavelengths, mainly because direct UV modulators remain li…
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…
