Hollow-core photonic crystal fibers for Power-over-Fiber systems
Jonas H. Osório, Joao B. Rosolem, Fabio R. Bassan +4
Research achievements in hollow-core photonic crystal fibers technology allow ascertaining such fibers as outstanding platforms for delivering high-power laser beams. Indeed, the k…
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…
Experimental phase control of a 100 laser beam array with quasi-reinforcement learning of a neural network in an error reduction loop
Maksym Shpakovych, Geoffrey Maulion, Vincent Kermene +4
An innovative scheme is proposed for the dynamic control of phase in two-dimensional laser beam array. It is based on a simple neural network that predicts the complex field array…
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…
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…
