I have always been curious to understand the physics behind ultrafast laser-matter interactions, particularly ultrafast laser processing and ultrafast spectroscopy. Precise material engineering with functional design responding to key challenges in the field of optics, mechanics, energy, and environment relies nowadays on critical developments of advanced photonics and intelligent system engineering, namely reconfigurable laser processing tools capable to adapt to shape and matter. A particularly interesting solution targets the smart design of 3D nanoscale morphologies in optical materials using automated programmable ultrafast laser processing approaches and feedback-assisted learning loops. Processes of matter-self-organization under light can thus be triggered and guided towards the definition of new pattern geometries with scale features and periodicities below 100nm, a cornerstone in advanced laser processing. This will lead to lots of advanced photonics applications like 5D data storage.
