Compact, intense attosecond sources driven by hollow Gaussian beams
Rodrigo Martín-Hernández, Melvin Redon, Ann-Kathrin Raab +9
High-order harmonic generation (HHG) enables the up-conversion of intense infrared or visible femtosecond laser pulses into extreme-ultraviolet attosecond pulses. However, the high…
