Coherent Beam Combination in Integrated Optics
Nonlinear Guided-Wave Phenomena Physics and Applications, 1989The coherent beam combination, or two-wave mixing, in nonlinear waveguide is a new area of great importance in integrated optics. The coherent beam combination has been successfully demonstrated in the bulk nonlinear materials, e.g., photorefractive1 or nonlocal Kerr materials,2 for image amplification,1,2 spectroscopy,3 etc.

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
