Segmented vortex wavefront coherent beam combining
AIP Advances, 2022 A concept of a coherent beam combining with a segmented vortex wavefront (V-CBC) was proposed to generate a dark optical trap. Three-dimensional (3D) irradiance distributions in the caustics of V-CBC were modeled.

Scaling potential of beam-splitter-based coherent beam combination
Optics Express, 2021 The impact of nonlinear refraction and residual absorption on the achievable peak- and average power in beam-splitter-based coherent beam combination is analyzed theoretically. While the peak power remains limited only by the aperture size, a fundamental average power limit is given by the thermo-optical and thermo-mechanical properties of the beam ...

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.
