Laser micro-engraving employs focused laser beams—often from ultrashort pulse (USP) lasers—to precisely ablate material surfaces. This results in crisp, accurate engravings often only visible under magnification, with minimal thermal impact.

Core Capabilities:

• Micron-level resolution and depth control
• Cold ablation with femtosecond/picosecond lasers
• Consistent high-speed performance
• Permanent, non-contact, tool-free operation
