Photonics, 2022 We report a coherent beam combining technique using a specific quasi-reinforcement learning scheme. A neural network learned by this method enables the tailoring and locking of a tiled beam array on any phase map.

Phasing methods of tiled-aperture coherent beam combining for high peak power lasers [PDF]
EPJ Web of Conferences, 2019 We demonstrate two type phasing methods for tiled-aperture coherent beam combining for high-power lasers based on the near and far field measurement techniques respectively, a comparison is made.

Passive Coherent Polarization Beam Combination of a Four-Fiber Amplifier Array
IEEE Photonics Journal, 2013 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
Journal of Synchrotron Radiation, 2023 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.

Probing the modal characteristics of novel beam shapes [PDF]
, 2013 In this thesis, an investigation into the modal characteristics of novel beam shapes is presented. Sculpting the phase profile of a Gaussian beam can result in the generation of a beam with unique properties.

Photonics, 2023 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]
EPJ Web of Conferences, 2023 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
Optics Communications, 2019 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.
