Tunable megawatt-scale sub-20 fs visible pulses from a fiber laser source
Mohammed Sabbah, Robbie Mears, Leah R. Murphy +4
Ultrafast laser pulses that are both tunable in wavelength and very short in duration are essential tools in fields ranging from biomedical imaging to ultrafast spectroscopy. While…
Low Spontaneous Brillouin Scattering in Anti-Resonant Hollow-Core Fibers in GHz Frequency Range
Ryan E. Dunagin, Robbie Mears, Dario Bueno-Baques +6
Brillouin light scattering (BLS) is a powerful experimental tool that can be used to get insights into the fundamental and applied properties of matter, like dispersions of quasipa…
Highly multi-mode anti-resonant hollow core fibres
Robbie Mears, Kerrianne Harrington, William J Wadsworth +2
We report the characterisation of anti-resonant hollow core optical fibres guiding at least 50 spatial modes in the infrared. Their propagation losses were measured to be between 0…
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…
