Small portions of metal layers can be precisely removed without any damage to the substrate using femtosecond laser pulses. Depth and geometry of ablation may vary, therefore it is suitable for variety of applications.

Applications of selective laser ablation of metal layers:
  • Lithography mask production
  • Beam shaping elements
  • Optical apertures
  • Diffractive gratings
  • Other
