Exploring novel capabilities of ultrafast lasers for surface finishing!
The versatility of ultrafast laser radiation is extended by a precision polishing process based on tailored surface melting. Significant advantages of ultrafast laser polishing are:
1. Surface roughness Ra < 100 nm
2. Lateral selectivity < 2 µm
3. Process speed > 10 cm²/min
4. Adjustable melt film thickness
5. Applicable under normal conditions
6. Integration into an ultrafast photonic process chain
