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…
Coherent combining of self-cleaned multimode beams
Marc Fabert, Maria Săpânţan, Katarzyna Krupa +9
A low intensity light beam emerges from a graded-index, highly multimode optical fibre with a speckled shape, while at higher intensity the Kerr nonlinearity may induce a spontaneo…
Nonlinear beam self-imaging and self-focusing dynamics in a GRIN multimode optical fiber: theory and experiments
Tobias Hansson, Alessandro Tonello, Tigran Mansuryan +7
Beam self-imaging in nonlinear graded-index multimode optical fibers is of interest for many applications, such as implementing a fast saturable absorber mechanism in fiber lasers…
