EUROPHOTON 2022

We report a new technique for phase control of tiled array of lasers based on a specific quasi-reinforcement learning approach. Principle and experiments on a seven-fiber amplifier laser array will be presented. We will show the dynamic locking of the laser phase relationship, and on-demand wavefront shaping.

Precise control of lasers is of critical importance for particle accelerators and free electron lasers. We discuss our approach to leverage the power of data science and artificial intelligence to improve the performance (pulse parameters, fast set-point tuning, stability) of our photocathode and pump-probe lasers.

We will present an overview on our research on novel multi-core fibers towards lasers and amplifiers for telecommunication, sensing as well as for scaling of coherently combined high power and high energy laser systems. We will link the required properties for the fibers to the manufacturing and characterization process chain.
