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…
Random scattering and alternating projection optimization for active phase control of a laser beam array
J. Saucourt, P. Armand, V. Kermene +2
A fraction of a laser beam array, whose unknown phase relationships must be set to prescribed values, is launched into a scattering media with random transmission. The resulting ou…
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…
Kerr beam self-cleaning on the mode in graded-index multimode fiber
E. Deliancourt, M. Fabert, A. Tonello +7
We report the experimental observation of Kerr beam self-cleaning in a graded-index multimode fiber, leading to output beam profiles different from a bell shape, close to the $LP_{…
Fast transmission matrix measurement of a multimode fiber with common path reference
Raphael Florentin, Vincent Kermene, AgnÈs Desfarges-berthelemot +1
We report an improved scheme for the measurement of the transmission matrix of multimode waveguides in which the reference field co-propagates with the signal wave. The performance…
Coherent combining in an Yb doped double core fiber laser
Johan Boullet, David Sabourdy, Agnès Desfarges-Berthelemot +5
Coherent combining is demonstrated in a clad pumped Yb doped double core fiber laser. A slope efficiency of more than 70 % is achieved with 96 % of the total output power on the fu…
