What materials can MOPA lasers mark?

MOPA lasers can mark a vast range of materials including metals (steel, aluminum, copper, brass, titanium), plastics (ABS, PC, PP), ceramics, and coated surfaces. They excel at producing high-contrast black marks on anodized aluminum and color annealing on stainless steel—something standard fiber lasers cannot achieve. Additionally, MOPA lasers can mark sensitive materials like thin films and electronic components without damage. Whether for automotive, medical, or consumer goods, MOPA technology offers the material compatibility you need for professional marking results.
