Designing Chromatically Corrected F-Theta Lenses for Ultrafast Materials Processing

Optical systems used with ultrafast lasers face unique challenges in terms of chromatic effects, back reflections, and group delay dispersion (GDD). Small details design considerations of a chromatically-corrected f-theta scanning lens used in ultrafast laser processing applications. This case study provides real examples of combatting both the unique challenges of designing ultrafast laser optics and considerations specific to f-theta lenses. Minimizing pulse distortions across the scan field is essential for maintaining laser focus intensity and quality.
