: We demonstrate generation of 7.6 fs near-UV pulses centered at 400 nm via 8-fold soliton-effect self-compression in an Ar-filled hollow-core kagomé-style photonic crystal fiber with ultrathin core walls. Analytical calculations of the effective compression length and soliton order permit adjustment of the experimental parameters, and numerical modelling of the nonlinear pulse dynamics in the fiber accurately predict the spectro-temporal profiles of the self-compressed pulses.

Efficient self-compression of ultrashort near-UV pulses in air-filled hollow-core photonic crystal fibers.

Generation of ultrashort near-UV pulses by soliton self-compression in kagomé-style hollow-core photonic crystal fibers filled with ambient air is reported, supported by numerical simulations, showing that both Raman and Kerr effects play a role in the compression dynamics.

UV soliton dynamics and Raman-enhanced supercontinuum generation in photonic crystal fiber

Ultrafast broadband ultraviolet radiation is of importance in spectroscopy and photochemistry, since high photon energies enable single-photon excitations and ultrashort pulses allow time-resolved

High-energy pulse self-compression and ultraviolet generation through soliton dynamics in hollow capillary fibres

Optical soliton dynamics can cause extreme alteration of the temporal and spectral shape of a propagating light pulse. This occurs at up to kilowatt peak powers in glass-core optical fibres and at

Ultrafast nonlinear optics in gas-filled hollow -core photonic crystal fibers

Ultrashort pulses in the near-infrared (NIR) to mid-infrared (MIR) are widely used for laser matter interaction experiments, e.g. the relaxation process of carrier semiconductors and chemical

Stimulated Raman Scattering in Hydrogen-Filled Hollow-Core Photonic Crystal Fiber

We report on stimulated Raman scattering in an approximately 1-meter-long hollow-core photonic crystal fiber filled with hydrogen gas under pressure. Light was guided and confined in the

Generation of microjoule pulses in the deep ultraviolet at megahertz repetition rates

Although ultraviolet (UV) light is important in many areas of science and technology, there are very few if any lasers capable of delivering wavelength-tunable ultrashort UV pulses at high repetition

Generation of tunable 7-fs ultraviolet pulses: achromatic phase matching and chirp management

Ultraviolet pulses with a duration of 7 fs are effi- ciently generated by frequency doubling the output of a non- collinear optical parametric amplifier. The ultraviolet pulses are tunable between

Single-mode solarization-free hollow-core fiber for ultraviolet pulse delivery.

It is demonstrated that the single-mode AR-HCF significantly outperforms commercially-available high-OH and solarization-resistant silica multimode fibers for pulsed light delivery in this spectral range.

Exceptional polarization purity in antiresonant hollow-core optical fibres

High-performance interferometers, gyroscopes, frequency combs, quantum information experiments and optical clocks rely on the transmission of light beams with the highest possible spatial and

Demonstration of a waveguide regime for a silica hollow--core microstructured optical fiber with a negative curvature of the core boundary in the spectral region > 3.5 μm.

It is shown that HC MOFs with the cladding consisting only of one row of silica capillaries allows to guide light from the near to mid infrared despite of high material losses ofsilica in this spectral region.
