Binary coherent beam combination with mirror pairs
Applied Optics, 2002A configuration of N coated mirrors or mirror pairs is described that has the potential to coherently combine 2N single-frequency phase-locked diffraction-limited polarized optical beams to form a single diffraction-limited beam. The application to beam combination of fiber amplifiers is discussed.

Reinforcement Learning for Coherent Beam Combining
CLEO Pacific Rim Conference, 2018Reinforcement learning has been shown to be capable of solving complex tasks. Here we show potential advantages and disadvantages in the context of phase control for coherent beam combining.

A non-uniformly coherent combining beam
Laser Physics, 2014An 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, 2018Coherent 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.

Coherent beam combining of fiber amplifiers
2003 Conference on Lasers and Electro-Optics Europe (CLEO/Europe 2003) (IEEE Cat. No.03TH8666), 2005In this paper, we demonstrate the coherent superposition of fiber amplifiers in a Michelson-type setup with active amplifying arms. The diffraction limited beam quality from the amplifiers is not reduced by imposing the beams and combining efficiencies exceeds 95%.

Dynamic beam shaping with coherent beam combining
PhotonicsViewsAbstractCoherent beam combining (CBC) is a method of enhancing laser power. It has recently transitioned to industrial applications, unveiling new possibilities in laser technology. CBC merges multiple laser channels from a single source, controlling their phase to create constructive or destructive interference.

Coherent beam combining of diode arrays
2013 High Power Diode Lasers and Systems Conference (HPD), 2013Summary form only given. There is continuing interest in increasing the power and improving the beam quality of laser sources for a variety of applications. An approach, particularly relevant to semiconductor and fiber lasers, is to beam combine large arrays of lasers.

Fiber Lasers and Their Coherent Beam Combination
Optics and Photonics News, 2008With high efficiency and exceptional beam quality, fiber lasers hold great promise. The 1-µm wavelength makes it possible for them to replace both diode- and lamp-pumped Nd:YAG lasers in the micromachining, automotive and biomedical markets.

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.
