Abstract
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.
