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.

A method to achieve spectral beam combining based on a novel symmetric grating
Frontiers in Physics, 2022 A symmetric grating is proposed to obtain higher output power in spectral beam combination by increasing the number of lasers and spectral utilization. The grating allows laser beams to be incident from both sides of the grating normal to achieve coaxial

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 ...

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
