This article offers an extensive survey of results obtained using hybrid photonic-crystal fibers
(PCFs) which constitute one of the most active research fields in contemporary fiber optics …

Here we demonstrate a high-power mid-infrared fiber gas Raman laser with a tunable
wavelength range of 2851 nm to 2921 nm in a deuterium-filled hollow-core fiber pumped by …

Femtosecond long-wave-infrared (LWIR) pulses have found applications in several fields,
but their generation is limited to CO _2 lasers and solid-state frequency converters …

Raman scattering has found renewed interest owing to the development of gas-filled hollow-
core fibers, which constitute a unique platform for exploration of novel ultrafast nonlinear …

We report on the generation of a purely vibrational Raman comb, extending from the
vacuum ultraviolet (184 nm) to the visible (478 nm), in hydrogen-filled kagomé-style …

In 1964 Bloembergen and Shen predicted that Raman gain could be suppressed if the rates
of phonon creation and annihilation (by inelastic scattering) exactly balance. This is only …

Coherent ultraviolet light has many uses, for example, in the study of molecular species
relevant in biology and chemistry. Very few, if any, laser materials offer ultraviolet …

We report the use of coherent anti-Stokes Raman spectroscopy (CARS) in gas-filled hollow-
core photonic crystal fiber (HC-PCF) for trace gas detection. The long optical path-lengths …

We report a fully integrated interface delivering efficient, reflection-free, single-mode, and
self-aligned coupling between a step-index fiber and a gas-filled hollow-core photonic …

Broadband-tunable sources of circularly polarized light are crucial in fields such as laser
science, biomedicine, and spectroscopy. Conventional sources rely on nonlinear …
