Coherent beam combining of fiber lasers
2017 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2017There is continuing interest in increasing the power and improving the beam quality of laser sources for a variety of applications including materials processing, pumping, power transmission, and illumination. One approach is to continue to develop improved lasers with higher power and good beam quality.

Coherent beam combination in optical waveguides
SPIE Proceedings, 1990A general theory for coherent coupling between two co-propagating or counterpropagating guided waves is formulated within the slowly varying envelope approximation. A pair of coupled nonlinear equations is obtained for the evolution of envelope functions. A numerical result is given for coherent coupling of two co-propagating pulses in a single mode

Generation of azimuthally and radially polarized beams by coherent polarization beam combination
Optics Letters, 2012A new architecture for generating pure azimuthally and radially polarized beams is presented. It involves coherent polarization beam combination of two orthogonally polarized LP(11) fiber modes. Experimental results reveal that high purely polarized (polarization purity of 95% or better) azimuthal and radial beams can be generated.

Coherent Beam Combining of Fiber Amplifiers*
Lasers Congress 2016 (ASSL, LSC, LAC), 2016Beam combining of laser arrays has become increasing viable over the past decade as the community has developed a better understanding of the requirements imposed by beam combining. Coherent beam combining (CBC) enables scaling the brightness by large amounts, in principle by as much as the number of elements.

Beam Shaping with Neural Network Coherent Beam Combination
Optica Laser Congress Congress 2025Three Yb-fiber amplifier outputs were phase-locked and beam-shaped in a tiled aperture CBC array using a neural network algorithm executed at 1100Hz, achieving low differential phase noise (40mrad, lambda/150) with beam shaping in a single step (1ms).

Noise scaling in coherent beam combination
High power fibre lasers find essential applications in scientific research and industrial manufacturing. Although the last few decades have witnessed an unprecedented rise in the output power scaling of fibre lasers, state-of-the-art technology offers quantum-noise-limited laser power only up to a few hundred Watts.openaire +1 more source
