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…
Studying the operation of an all-PM Yb-doped fiber laser oscillator at negative and positive net cavity dispersion
Mateusz Pielach, Jan Szczepanek, Katarzyna Krupa +1
Chirped fiber Bragg gratings in Yb-doped fiber lasers allow tuning the net cavity dispersion, thus enabling access to pulse dynamics beyond the typical all-normal-dispersion dissip…
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…
Energy and wave-action flows underlying Rayleigh-Jeans thermalization of optical waves propagating in a multimode fiber
K. Baudin, A. Fusaro, J. Garnier +6
The wave turbulence theory predicts that a conservative system of nonlinear waves can exhibit a process of condensation, which originates in the singularity of the Rayleigh-Jeans e…
Dramatic acceleration of wave condensation mediated by disorder in multimode fibers
Adrien Fusaro, Josselin Garnier, Katarzyna Krupa +2
Classical nonlinear waves exhibit a phenomenon of condensation that results from the natural irreversible process of thermalization, in analogy with the quantum Bose-Einstein conde…
Wave condensation with weak disorder versus beam self-cleaning in multimode fibers
J. Garnier, A. Fusaro, K. Baudin +4
Classical nonlinear random waves can exhibit a process of condensation. It originates in the singularity of the Rayleigh-Jeans equilibrium distribution and it is characterized by t…
