Carefully Controlled Laser Processing for the Finest Structures

Diamond Laser Cutting through Layer-by-Layer Ablation

Diamonds are the world’s hardest material but are sensitive to high-temperature gradients and tend to crack when processed. Traditional manufacturing processes like wire-based electrical discharge machining make diamond cutting a time-consuming process with high tool wear.

Diamond laser cutting shortens machining time considerably. Due to the extremely short laser pulses, the material can be removed without thermally damaging the remaining material. This enables a high-quality result with cut edges that have a low surface roughness.
