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

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.

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.

Transverse beam combiner for ILSE [PDF]
Il Nuovo Cimento A, 1993 Previous heavy-ion fusion driver system studies suggest that transverse beam combining significantly reduces driver cost. In a combiner, several beams are brought together to a common transport channel which accommodates the increased line charge density.
