Plenary Lecture

10 kW-class ultrashort-pulse lasers for industrial applications

Tuesday (23.06.2020)
13:30 - 14:10 Room 1

13:30 - 14:10

The Fraunhofer Cluster of Excellence Advanced Photon Sources (CAPS) will overcome USP laser power limitations, but also develop technologies along the process chain from pulse generation to process technology, and real-world applications.

In the presentation we will report on the most recent progress in scaling the average output power of femtosecond lasers beyond the 10kW barrier. Two technological paths will be described, coherently combined fiber amplifiers and the Innoslab approach. System performance as well as future perspectives will be reviewed.

In parallel to the laser sources, beam delivery technology is developed to make effective use of the radiation. While the CAPS-partners develop a range of new technologies, their ambition is actually to make the USP laser a tool with average powers of current CW fiber lasers plus the unique features of USP lasers, including high precision and low or no dependency from the processed material.
