Journal ArticleDOI
Coherent anti-Stokes Raman scattering microscopy with a photonic crystal fiber based light source
TL;DR: In this paper, a coherent anti-Stokes Raman scattering (CARS) microscopy was demonstrated using a light source consisting of the output from a photonic crystal fiber pumped by a standard Ti:sapphire oscillator and the fundamental oscillator beam.

TL;DR: In this paper, the authors reported experimental results on x-ray diffraction of quantum-state-selected and strongly aligned ensembles of the prototypical asymmetric rotor molecule 2,5-diiodobenzonitrile using the Linac Coherent Light Source.
Journal ArticleDOI
Supercontinuum generation in ZBLAN fibers—detailed comparison between measurement and simulation
Christian Agger,Christian Petersen,Sune Dupont,Henrik Steffensen,Jens K. Lyngsø,Carsten L. Thomsen,Jan Thøgersen,Søren Rud Keiding,Ole Bang +8 more
TL;DR: In this article, a detailed comparison between modeling and experiments on supercontinuum (SC) generation in a commercial ZBLAN step-index fiber is presented, with special emphasis on identifying accurate material parameters by incorporating measurements of the Raman gain, fiber dispersion, and loss.
Journal ArticleDOI
IR microscopy utilizing intense supercontinuum light source.
TL;DR: In infrared supercontinuum radiated from an optical fiber as a promising new light source for infrared microspectroscopy, which allows contact free high resolution hyper spectral infrared microscopy.
Journal ArticleDOI
Continuous-wave wavelength conversion in a photonic crystal fiber with two zero-dispersion wavelengths
T.V. Andersen,Karen Marie Hilligsøe,Carsten Krogh Nielsen,Jan Thøgersen,Kim P. Hansen,Søren Rud Keiding,Jakob Juul Larsen +6 more
TL;DR: Continuous-wave wavelength conversion through four-wave mixing in an endlessly single mode photonic crystal fiber is demonstrated and phasematching is possible at vanishing pump power in the anomalous dispersion regime between the two zero-dispersion wavelengths.
