We report on kW-level femtosecond lasers for flexible and high throughput industrial applications. Power scaling is achieved by a slab-based amplifier architecture. 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.
We report on femtosecond lasers with more than one kilowatt of average output power and pulse energies around 10 mJ. Power scaling is enabled by scaling the crystal dimensions of the slab-like amplifier crystal as well as by applying multi-stage booster amplifier configurations. The demonstrated femtosecond laser is aimed to serve in high throughput industrial applications in the aerospace industries in order to generate hybrid laminar flow controlled structures. Further industrial and scientific applications will be reviewed as well.
