Femtosecond lasers have over the past ten years seen a tremendous increase in average power, with industrial laser reaching today the kW level. At the same time new applications are continuously emerging in various industrial sectors: health, production, energy, transport. Femtosecond laser processing is today a technology enabling large volume, high precision industrial manufacturing. The "agility" of lasers and associated beam engineering now available, enables flexible, reconfigurable production. High average power femtosecond lasers allow higher productivity and thus open access to new and large markets unreachable so far (Aeronautics, Energy and Mobility, etc.). Making full use of the available average power without losing the high quality of ultrafast laser processing is not straightforward and require advances in laser design and associated beam engineering. For instance, high laser repetition rate up to 10 MHz or temporal shaping of the pulse train with busts of pulses, allows specific process optimization with the use of beam deviation at very high speed if suited pulses synchronisation is possible. Spatial shaping, for instance by dividing a single high-power beam into multiple beamlets, will be also a “must have” in the following years. Fixed diffractive optics (DOE), user configurable optical tools (spatial light modulators, SLM, or AOM), and new shaping systems using multi-plane light conversion (MPLC) technology allow flexibility to transform both phase and amplitude of a laser beam without major losses.
