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.

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 ...

Coherent beam combining of 61 femtosecond fiber amplifiers.
Optics Express, 2020 We report on the coherent beam combining of 61 femtosecond fiber chirped-pulse amplifiers in a tiled-aperture configuration along with an interferometric phase measurement technique. Relying on coherent beam recombination in the far field, this technique

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.

A phase-error prediction method for coherent beam combining via convolutional neural network
, 2021 Coherent beam combination (CBC) with Actively Phase-Controlling is a key method to many applications. The core challenge of achieving a Diffraction-Limited output laser of CBC is to correct and lock the phase errors quickly between the sub-beams. A phase
