Supercontinuum generation in methane-filled hollow-core antiresonant fiber
Balazs Plosz, Athanasios Lekosiotis, Mohammad Sabbah +3
We report the generation of a multi-octave supercontinuum spanning from 350 nm to 1700 nm with exceptional spectral flatness and high conversion efficiency to both the visible and…

On-target delivery of intense ultrafast laser pulses through hollow-core anti-resonant fibers
Athanasios Lekosiotis, Federico Belli, Christian Brahms +5
We report the flexible on-target delivery of 800 nm wavelength, 5 GW peak power, 40 fs duration laser pulses through an evacuated and tightly coiled 10 m long hollow-core nested an…

Ultrafast circularly polarized pulses tunable from the vacuum to deep ultraviolet
Athanasios Lekosiotis, Christian Brahms, Federico Belli +2
We experimentally demonstrate the efficient generation of circularly polarized pulses tunable from the vacuum to deep ultraviolet (160-380 nm) through resonant dispersive wave emis…
