Phase amplification microscopy with femtometer-level accuracy
Nansen Zhou, Qihang Zhang, Ting Huang +12
We demonstrate a major breakthrough in laser interferometry and microscopy achieving femtometer-level measurement accuracy and beyond, termed Phase Amplification microscopy (Φ-Amp…
Robustness Optimization for Compact Free-electron Laser Driven by Laser Wakefield Accelerators
Hai Jiang, Ke Feng, Runshu Hu +3
Despite the successful demonstration of compact free electron lasers (FELs) driven by laser wakefield accelerators (LWFAs), the inherent shot-to-shot fluctuations in LWFAs, includi…
Twisting harmonics: Transfer of orbital angular momentum in solid-state high-harmonic generation
Debobrata Rajak, Bikash Kumar Das, Rajaram Shrestha +7
Although solid-state platforms underpin modern electronics, little is known about how intense ultrashort light pulses carrying orbital angular momentum (OAM) interact with solids.…
Sculpting ultrafast mid-infrared light for solid-state high harmonic generation
Camilo Granados, Bálint Kiss, Eric Cormier +6
The ability to sculpt light in space, time, and polarization has revolutionized studies of light-matter interaction and enabled breakthroughs in optical communication, imaging, and…
Annular Channel Eigenmodes: A Physical-Layer Approach to Suppressing OAM Modal Crosstalk
Chenghao Li, Pengyang An, Ziao Huang +2
Modal crosstalk is a fundamental limitation for orbital angular momentum (OAM)-based spatial-division multiplexing. Here, we introduce Annular Channel Eigenmodes (ACEs) - rigorousl…
