The standard quantum limit of coherent beam combining
New Journal of Physics, 2019 Coherent beam combining refers to the process of generating a bright output beam by merging independent input beams of individually diffusing relative phases by locking them to each other.

Coherent beam combining of optical vortices
, 2023 We experimentally demonstrate the power scaling of optical vortices by the coherent beam combining, encompassing topological charges ranging from l=1 to l=5 realized on the basis of a Yb-doped fiber short-pulsed laser system. The combining efficiency varies from 83.2 to 96.9% depending on the topological charge and beam pattern quality generated by the

Coherent beam combining of optical vortices
Optics LettersWe experimentally demonstrate the power scaling of optical vortices using the coherent beam combining technique, encompassing topological charges ranging from ℓ = 1 to ℓ = 5 realized on the basis of a Yb-doped fiber short-pulsed laser system. The combining efficiency varies from 83.2 to 96.9% depending on the topological charge and beam pattern quality

Coherent Beam Combining Using an Internally Sensed Optical Phased Array of Frequency-Offset Phase Locked Lasers [PDF]
Photonics, 2020 Coherent beam combining can be used to scale optical power and enable mechanism-free beam steering using an optical phased array. Coherently combining multiple free-running lasers in a leader-follower laser configuration is challenging due to the need to

Phasing methods of tiled-aperture coherent beam combining for high peak power lasers [PDF]
EPJ Web of Conferences, 2019 We demonstrate two type phasing methods for tiled-aperture coherent beam combining for high-power lasers based on the near and far field measurement techniques respectively, a comparison is made.

Impact of atmospheric turbulence on coherent beam combining for laser weapon systems
Defence Technology, 2021 The performance of a laser weapon system based on coherent beam combining (CBC) depends on its propagation properties in the atmosphere. In this study, an analytical model based on partial coherent beam combining (PCBC) for assumed coherence coefficients

The generation and verification of Bessel-Gaussian beam based on coherent beam combining
Results in Physics, 2020 We propose a method to generate Bessel-Gaussian (BG) beam by Gaussian beam array where beamlets are arranged along a circle. The phase difference between adjacent beamlets is a constant, and the total phase increment is equal to 2πl (l is integer). Based

Discussion on Piston-Type Phase Ambiguity in a Coherent Beam Combining System
Photonics, 2022 Coherent beam combining (CBC) with closely arranged centrosymmetric arrays is a promising way to obtain a high-brightness laser. An essential task in CBC is to actively control the piston phases of the input beams, maintaining the correct phasing to ...

Investigation of the coherent combination of a 19-fiber laser beam characteristics to achieve a multi tens of kW at a distance of 10 km [PDF]
مجله علوم و فنون هستهای, 2019 In this paper, we used a coherent beam combination to design a 50 kW high power laser beam for energy applications. Because of the strong environmental turbulence, degrade the coherent beam combination advantages, low turbulence level is considered ...
