Coherent beam combining of optical vortices
We experimentally demonstrate the power scaling of optical vortices using the coherent beam combining technique, encompassing topological charges ranging from ℓ = 1 to ℓ = 5 realized on the basis of a Yb-doped fiber short-pulsed laser system. The combining efficiency varies from 83.2 to 96.9% depending on the topological charge and beam pattern quality

Passive Coherent Polarization Beam Combination of a Four-Fiber Amplifier Array
We present what we believe to be a new architecture for coherent beam combination of a fiber amplifier array. Four polarization-maintained fiber amplifiers are passively coherent polarization beam combined by using an optical feedback in a ring cavity ...

Multiplexed emitting system for an energy-recovery-linac-based coherent light source
Recently, a novel approach has been proposed to produce ultrashort, fully coherent high-repetition-rate EUV and X-ray radiation by combining an energy recovery linac (ERL) with the angular-dispersion-induced microbunching methodology.

A coherent beam combination has the potential to revolutionize high-peak-power laser systems. However, achieving a high-average-power ultrashort pulse is difficult due to the accumulation of a nonlinear phase and gain narrowing.

HIBISCUS: Simulator for the development of control strategies for coherent beam combining lasers with PISTIL technique [PDF]
CBC (Coherent Beam Combining) is a key technology for the realisation of intense lasers. In this context, PISTIL (PISton and TILt interferometry), a precise metrology tool for measuring segmented wave surfaces, has been developed and used in particular ...

Effect of beam profile and partial coherence on coherent beam combining performance
Abstract A numerical model of a coherent beam composed of a two-dimensional array of laser beams was developed; the model enables analysis of random phase mismatch in the combined system, as well as analysis of the influence of atmospheric turbulence.

In our research, we propose a novel asymmetric multiple-image encryption method using a conjugate Dammann grating (CDG), which is based on the coherent beam combining (CBC) principle.

Study of high power CBC fiber laser systems with non-equal splitting ratio beam-splitters
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.

Multi-plane light conversion coherent beam combining
Multi-plane light conversion (MPLC) is a versatile technique that enables arbitrary manipulation of optical fields, and is numerically investigated as a novel avenue for coherent beam combining (CBC) applications.
