Numerical analysis of beam self-cleaning in multimode fiber amplifiers
Mesay Addisu Jima, Alessandro Tonello, Alioune Niang +6
Recent experimental results have reported the observation of beam self-cleaning or, more generally, nonlinear beam reshaping in active multimode fibers. In this work we present a n…
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…
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…
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…
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…
