High-efficiency narrowband terahertz generation in novel wide-bandgap barium chalcogenide crystals
D. Z. Suleimanova, E. A. Migal, D. V. Badikov +1
We report on extensive experimental investigation of novel barium chalcogenides (BaGa4Se7, BaGa2GeSe6 and BaGa2GeS6) for generation of a strong narrowband terahertz (THz) radiation…

Moderate-terahertz-induced plateau expansion of high-order harmonic generation to soft X-ray region
Doan-An Trieu, Duong D. Hoang-Trong, Cam-Tu Le +5
Extending the high-harmonic cutoff with experimentally accessible fields is essential for advancing tabletop coherent extreme ultraviolet (EUV) and soft X-ray sources. Although ter…
