Abstract Hollow‐core fiber (HCF), in which> 99.99% of the light is guided in a central air (or
vacuum) filled core, is a radically new fiber technology offering the potential to overcome the …

A main, yet-unsolved challenge in splicing hollow-core fiber (HCF) into standard single-
mode fiber (SMF) systems lies in managing the strong Fresnel back-reflection that occurs …

In this work, multi-mode anti-resonant hollow-core fiber (AR-HCF) with 18 fan-shaped
resonators is fabricated and characterized. The ratio of core diameter over transmitted …

Raman scattering is the inelastic process where photons bounce off molecules, losing
energy and becoming red-shifted. This weak effect is unique to each molecular species …

In this paper we explore the application of low-loss multimode anti-resonant hollow-core
fiber (MM-AR-HCF) in the delivery of nanosecond laser pulses at 1? µm wavelength. MM-AR …

In this paper, we experimentally asses the performance of wavelength modulation
spectroscopy-based spectrometers incorporating 1.3 m-long gas absorption cells formed by …

We investigate the design of hollow-core fibers for the delivery of 10s of kilowatt average
power from multi-mode laser sources where delivery through solid-core fibers is typically …

A fiber‐based approach that generates mid‐infrared femtosecond pulses in the 3–4 μ \umu
m spectral region with microjoule‐level single pulse energy is demonstrated. This is realized …

Ultrafast laser sources in the far ultraviolet (100–300 nm) have been the subject of intense
experimental efforts for several decades, driven primarily by the requirements of advanced …
