Frequency-Resolved Spatial Beam Mapping in Multimode Fibers: Application to Mid-Infrared Supercontinuum Generation
Y. Leventoux, G. Granger, K. Krupa +6
We present a new spatial-spectral mapping technique permitting to measure the beam intensity at the output of a graded-index (GRIN) multimode fiber with sub-nanometric spectral res…
Femtosecond nonlinear losses in multimode optical fibers
Mario Ferraro, Fabio Mangini, Mario Zitelli +4
Research on multimode optical fibers is arousing a growing interest, for their capability to transport high-power laser beams, coupled with novel nonlinear optics-based application…
Spatiotemporal beam self-cleaning for high-resolution nonlinear fluorescence imaging with multimode fibres
Nawell Ould Moussa, Tigran Mansuryan, Charles Henri Hage +12
Beam self-cleaning (BSC) in graded-index (GRIN) multimode fibres (MMFs) has been recently reported by different research groups. Driven by the interplay between Kerr effect and bea…
3D time-domain beam mapping for studying nonlinear dynamics in multimode optical fibers
Y. Leventoux, G. Granger, K. Krupa +8
The characterization of the complex spatiotemporal dynamics of optical beam propagation in nonlinear multimode fibers requires the development of advanced measurement methods, capa…
Giving light a new twist with standard optical fibres: rainbow Archimedean spiral emission
F. Mangini, M. Ferraro, M. Zitelli +8
We demonstrate a new practical approach for generating multicolour spiral-shaped beams. It makes use of a standard silica optical fibre, combined with a titled input laser beam. Th…
Multiphoton absorption excited upconversion luminescence in optical fiber
F. Mangini, M. Ferraro, M. Zitelli +4
We experimentally demonstrate a novel nonlinear effect in optical fibers: upconversion luminescence generation excited by multiphoton absorption of femtosecond infrared pulses. We…
