Extreme water repellency by PERLA laser
„Teaming for Success“
Conversion to VIS/DUV▪ Assets of PERLA C fundamental beam for HG:
High average output (100-500 W) + Picosecond pulses (1-10 ps)
Application of harmonics:▪ Material processing: low heat loading → photo-ablation → cutting & microdrilling with
precise and high density structuring▪ Scientific applications (DUV): semiconductor lithography, photoemission from metal cathodes at
accelerator devices, promotion of surface phase transitions
