TL;DR: In this article, a record-breaking spectral coverage of 1.4-13.3 µm was achieved by launching intense ultra-short pulses into short pieces of ultra-high numerical aperture step-index chalcogenide glass optical fiber consisting of a GaAsSe cladding and an As2Se3 core.
Journal ArticleDOI
Multi-milliwatt mid-infrared supercontinuum generation in a suspended core chalcogenide fiber
Uffe Møller,Yi Yu,Irnis Kubat,Christian Rosenberg Petersen,Xin Gai,Laurent Brilland,David Mechin,Celine Caillaud,Johann Troles,Barry Luther-Davies,Ole Bang +10 more
TL;DR: A low-loss suspended core As(38)Se(62) fiber with core diameter of 4.5 μm and a zero-dispersion wavelength of 3.5μm was used for mid-infrared supercontinuum generation and was in good correspondence with the calculated dispersion.
Journal ArticleDOI
Real-time high-resolution mid-infrared optical coherence tomography.
Niels Møller Israelsen,Christian Rosenberg Petersen,Ajanta Barh,Deepak Jain,Mikkel Jensen,Günther Hannesschläger,Peter Tidemand-Lichtenberg,Christian Pedersen,Adrian Gh. Podoleanu,Ole Bang +9 more
TL;DR: In this paper, a mid-infrared spectral-domain optical coherence tomography (OCT) system operating at a central wavelength of 4'µm and an axial resolution of 8.6' µm is demonstrated.
Journal ArticleDOI
Thulium pumped mid-infrared 0.9-9μm supercontinuum generation in concatenated fluoride and chalcogenide glass fibers.
Irnis Kubat,Christian Rosenberg Petersen,Uffe Møller,Angela B. Seddon,Trevor M. Benson,Laurent Brilland,David Mechin,Peter M. Moselund,Ole Bang +8 more
TL;DR: A novel approach for generating Mid-InfraRed SuperContinuum (MIR SC) by using concatenated fluoride and chalcogenide glass fibers pumped with a standard pulsed Thulium laser is theoretically demonstrated.
Journal ArticleDOI
Mid-infrared multispectral tissue imaging using a chalcogenide fiber supercontinuum source.

TL;DR: Tissue imaging was demonstrated in transmission at selected wavelengths between 5.7 and 7.3 μm by point scanning over a sub-millimeter region of colon tissue, and the results were compared to images obtained from a commercial instrument.
