Coherent Beam Combining of Fiber Amplifiers*

Lasers Congress 2016 (ASSL, LSC, LAC), 2016
Beam 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.

A non-uniformly coherent combining beam

Laser Physics, 2014
An approach that can be used to generate more complex and interesting optical fields is proposed by controlling the phase, position, size and amplitude of each coherent array. To illustrate the advantages of the approach, the power coupling efficiency of the optical systems with Cassegrain-telescope receivers is studied.

Coherent Beam Combining of Fiber Lasers

CLEO Pacific Rim Conference, 2018
Coherent beam combination has been established as a performance scaling concept for laser systems to overcome limitations of a single emitter. Today, the most powerful femtosecond fiber lasers employ his technique.

Beam Shaping with Neural Network Coherent Beam Combination

Optica Laser Congress Congress 2025
Three 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.
