TL;DR: In this article, a dispersion-managed all-fiber laser delivering ∼85 fs pulses at 1550 nm, passively mode-locked at the 178th harmonic (repetition rate 1.872 GHz) by intense optoacoustic interactions in a photonic crystal fiber (PCF) core.
Abstract: We report a dispersion-managed all-fiber laser delivering ∼85 fs pulses at 1550 nm, passively mode-locked at the 178th harmonic (repetition rate 1.872 GHz) by intense optoacoustic interactions in a photonic crystal fiber (PCF) core.

TL;DR: In this paper, the first generation of three-cycle, 8 fs, 125 mJ optical pulses in a noncollinear optical parametric chirped-pulse amplifier (NOPCPA) operating at 805 nm central wavelength was reported.
Abstract: We report the first generation of three-cycle, 8 fs, 125 mJ optical pulses in a noncollinear optical parametric chirped-pulse amplifier (NOPCPA) operating at 805 nm central wavelength. These 16 TW laser pulses are compressed to within 5% of their Fourier limit. These parameters come in combination with an amplified pulse contrast-ratio of 10−5 at Δt=±5ps and ≫10−7 at t≪−5ps limited by the detection barrier. Numerical split-step simulations are performed to investigate potential improvements for the NOPCPA laser system.

TL;DR: In this article, the diameter of a submicron air-clad waveguide was measured to nanometer precision, based on parametric amplification of a broadband seed signal, using a parametric pump and seed pulses.
Abstract: We report non-destructive measurement of the diameter of submicron air-clad waveguides to nanometer precision, based on parametric amplification of a broadband seed signal. Ultrashort pump and seed pulses allow the diameter to be longitudinally resolved.

TL;DR: In this article, it was shown that matter-wave solitary pulses formed from Bose condensed atoms in optical lattices continuously radiate dispersive matter waves, and that this radiation exists universally for solitons moving through the lattice with arbitrary small but non-zero velocities.

TL;DR: In a soliton fiber laser incorporating three different PCF sections and optomechanically mode-locked at around 1.94 GHz, the three acoustic core resonances are strongly driven, coupled and phase-locked by the sequence of laser pulses.

TL;DR: The field of cavity optomechanics explores the interaction between electromagnetic radiation and nano-or micromechanical motion as mentioned in this paper, which explores the interactions between optical cavities and mechanical resonators.
Abstract: We review the field of cavity optomechanics, which explores the interaction between electromagnetic radiation and nano- or micromechanical motion This review covers the basics of optical cavities and mechanical resonators, their mutual optomechanical interaction mediated by the radiation pressure force, the large variety of experimental systems which exhibit this interaction, optical measurements of mechanical motion, dynamical backaction amplification and cooling, nonlinear dynamics, multimode optomechanics, and proposals for future cavity quantum optomechanics experiments In addition, we describe the perspectives for fundamental quantum physics and for possible applications of optomechanical devices

TL;DR: In this article, a periodic array of microscopic air holes that run along the entire fiber length are used to guide light by corralling it within a periodic arrays of microscopic holes.
Abstract: Photonic crystal fibers guide light by corralling it within a periodic array of microscopic air holes that run along the entire fiber length Largely through their ability to overcome the limitations of conventional fiber optics—for example, by permitting low-loss guidance of light in a hollow core—these fibers are proving to have a multitude of important technological and scientific applications spanning many disciplines The result has been a renaissance of interest in optical fibers and their uses

TL;DR: In this article, a fast Fourier transform method of topography and interferometry is proposed to discriminate between elevation and depression of the object or wave-front form, which has not been possible by the fringe-contour generation techniques.
Abstract: A fast-Fourier-transform method of topography and interferometry is proposed. By computer processing of a noncontour type of fringe pattern, automatic discrimination is achieved between elevation and depression of the object or wave-front form, which has not been possible by the fringe-contour-generation techniques. The method has advantages over moire topography and conventional fringe-contour interferometry in both accuracy and sensitivity. Unlike fringe-scanning techniques, the method is easy to apply because it uses no moving components.

TL;DR: In this paper, a review of numerical and experimental studies of supercontinuum generation in photonic crystal fiber is presented over the full range of experimentally reported parameters, from the femtosecond to the continuous-wave regime.
Abstract: A topical review of numerical and experimental studies of supercontinuum generation in photonic crystal fiber is presented over the full range of experimentally reported parameters, from the femtosecond to the continuous-wave regime. Results from numerical simulations are used to discuss the temporal and spectral characteristics of the supercontinuum, and to interpret the physics of the underlying spectral broadening processes. Particular attention is given to the case of supercontinuum generation seeded by femtosecond pulses in the anomalous group velocity dispersion regime of photonic crystal fiber, where the processes of soliton fission, stimulated Raman scattering, and dispersive wave generation are reviewed in detail. The corresponding intensity and phase stability properties of the supercontinuum spectra generated under different conditions are also discussed.
