Journal ArticleDOI
Non-linear applications of microstructured optical fibres
TL;DR: In this paper, the authors extend the region of short wavelength operation of high power supercontinuum generation through four wave mixing in a cascaded fiber geometry where the dispersion of each fibre decreased on propagation.
Proceedings ArticleDOI
High power 29 W CW supercontinuum source
TL;DR: In this article, the authors reported a 29 W CW supercontinuum spanning from 1.07 μm to 1.67 μm with a spectral power density of 50 mW/nm up to 2.4 μm.
Proceedings ArticleDOI
Nonlinear optics and frequency conversion: fiber lasers in IR, VIS and UV
TL;DR: In this paper, a technique employing long lengths of tapered PCFs that allow efficient phase matched four wave mixing to the short-wavelength region was developed, which achieved spectral power densities as high as 5mW/nmin.
Proceedings ArticleDOI

TL;DR: High speed, three-dimensional optical coherence tomography at 800nm, 1060nm and 1300nm with approximately 4μm, 7μm and 6μm axial and less than 15μm transverse resolution is demonstrated to investigate the optimum wavelength region for in vivo human skin imaging in terms of contrast, dynamic range and penetration depth.
Journal ArticleDOI
Stochastic phenomena in a fiber Raman amplifier
Vladimir L. Kalashnikov,Vladimir L. Kalashnikov,Sergey Sergeyev,Juan Diego Ania-Castanon,Gunnar Jacobsen,Sergei Popov +5 more
TL;DR: In this article, the mapping of the Raman scattering-based nonlinearity, the random birefringence of a fiber, and the pump-to-signal intensity noise transfer has been done in terms of the fiber Raman amplifier parameters, namely polarization mode dispersion, the relative intensity noise of the pump laser, fiber length, and signal power.
