Abstract

We report on kW femtosecond lasers that will enable large scale and high productivity industrial applications. Power scaling is achieved by an Innoslab amplifier followed by slab-based booster amplifier stages. The laser concept is capable to generate high pulse energies in the multi-mJ range as well as high pulse repetition rates in the MHz or GHz ranges. Moreover, free triggering (FemtoTrig®) and burst options as well as frequency conversion to the green and UV spectral region will leverage these femtosecond lasers into future industrial applications. Also in the scientific domain these lasers will have a strong impact, e.g. as pump sources for powerful OPAs or high harmonics generation at high photon flux.
