Scalable Acoustical Frequency Tagging Coherent Beam Combining Based on Digital Signal Processing
IEEE Access, 2023 We present the module of booster amplifier for coherent beam combining Master Oscillator Power Amplifier (MOPA) system to operate with a text narrow-linewidth seed laser. The goal was to achieve a highly modular system, manifested in the ease of changing

Coherent combining of self-cleaned multimode beams [PDF]
Scientific Reports, 2020 AbstractA low intensity light beam emerges from a graded-index, highly multimode optical fibre with a speckled shape, while at higher intensity the Kerr nonlinearity may induce a spontaneous spatial self-cleaning of the beam. Here, we reveal that we can generate two self-cleaned beams with a mutual coherence large enough to produce a clear stable ...

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

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 ...

Intense vortical-field generation using coherent superposition of multiple vortex beams
Scientific Reports, 2023 Coherent beam combining technology applied to multiple vortex beams is a promising method to generate high-power vortex beams. We utilize the coherent combination of multiple Laguerre-Gaussian beams at the waist plane and propose theoretically a ...

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.

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.
