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…

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…

High-energy soliton fission dynamics in multimode GRIN fiber

Mario Zitelli, Fabio Mangini, Mario Ferraro +3

The process of high-energy soliton fission is experimentally and numerically investigated in a graded-index multimode fiber. Fission dynamics is analyzed by comparing numerical obs…
