Nonlinear combining of laser beams [PDF]
Optics Letters, 2014 We propose to combine multiple laser beams into a single diffraction-limited beam by the beam self-focusing (collapse) in the Kerr medium. The beams with the total power above critical are first combined in the near field and then propagated in the optical fiber/waveguide with the Kerr nonlinearity.

High Brightness Diode Lasers Based on Beam Splitting and Polarization Combining
Applied Sciences, 2022 A new method to improve the brightness of diode lasers based on beam-waist splitting and polarization combining was proposed and demonstrated. The beam waist was split by a precisely cut prism into two parts and combined with a polarization beam combiner.

Study of high power CBC fiber laser systems with non-equal splitting ratio beam-splitters
Results in Optics, 2023 High power coherent beam combination (CBC) with non-equal splitting ratio beam splitters (BS) is studied. A BS-based two-channel CBC laser system has been built, and experiments with 50:50 BS and 30:70 BS has been carried.

Generation of perfect vectorial vortex beams by employing coherent beam combining.
Optics Express, 2023 Based on coherent beam combining, we propose a method for generating the perfect vectorial vortex beams (VVBs) with a specially designed radial phase-locked Gaussian laser array, which is composed of two discrete vortex arrays with right-handed (RH) and ...
