Ultra-broadband transient absorption down to 200 nm enabled by soliton dynamics in gas-filled hollow capillary fibers
Pieter J. Brongers, Kyle Barlow, Deepjyoti Satpathy +3
The deep ultraviolet (DUV) window (200-300 nm) is essential for the characterization of (bio)chemical and material systems through the UV signatures of nucleobases, amino acids, pe…

Resonance-free deep ultraviolet to near infrared supercontinuum generation in a hollow-core antiresonant fibre
Mohammed Sabbah, Robbie Mears, Kerrianne Harrington +4
Supercontinuum generation in the ultraviolet spectral region is challenging in solid-core optical fibres due to solarization and photodarkening. Antiresonant hollow-core fibres hav…

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…
