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…
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…
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…
Spatial beam self-cleaning in tapered Yb-doped GRIN multimode fiber with decelerating nonlinearity
A. Niang, D. Modotto, A. Tonello +12
We experimentally demonstrate spatial beam self-cleaning in an Yb-doped graded-index multimode fiber taper, both in passive and active configurations. The input laser beam at 1064…
Spatial beam self-cleaning in multimode lanthanum aluminum silicate glass fiber
Romain Guénard, Katarzyna Krupa, Alessandro Tonello +11
We demonstrated that spatial Kerr beam self-cleaning can be obtained in a highly multimode multicomponent optical fiber based on lanthanum aluminum silicate oxide glasses (SiO2-Al2…
Wavefront shaping for optimized many-mode Kerr beam self-cleaning in graded-index multimode fiber
E. Deliancourt, M. Fabert, A. Tonello +7
We report experimental results, showing that the Kerr beam self-cleaning of many low-order modes in a graded-index multimode fiber can be controlled thanks to optimized wavefront s…
