Coherent beam combining with micro-lens arrays [PDF]
Optics Letters, 2020 A novel, to the best of our knowledge, concept for coherent beam combining is presented based on a simple setup with micro-lens arrays. These standard components are used in a proof-of-principle experiment for both coherent beam splitting and a combination of 5 × 5 beams. Here a combination efficiency above 90% is achieved.

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 ...

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 ...

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 ...

Electron beam profile imaging in the presence of coherent optical radiation effects
Physical Review Special Topics. Accelerators and Beams, 2012 High-brightness electron beams with low energy spread at existing and future x-ray free-electron lasers are affected by various collective beam self-interactions and microbunching instabilities. The corresponding coherent optical radiation effects, e.g.,

Resonant spin Hall effect of light in random photonic arrays
SciPost Physics, 2023 It has been recently shown that the coherent component of light propagating in transversally disordered media, the so-called coherent mode, exhibits an optical spin Hall effect (SHE).
