Fiber lasers are best suited for high-contrast markings like metal annealing, etching, and engraving. They produce an extremely small focal diameter (resulting in intensity up to 100 times higher than a CO2 system), making them the ideal choice for permanent marking of serial numbers, barcodes, and data matrix on metals.

Fiber lasers are widely used for product traceability (direct part marking) and identification applications.
This process is used in a wide range of application. The most common are deep logo engraving, stamping plate engraving and mold insert engraving(especially for automotive parts)
Can also be include high-value metal part like custom knobs and guns.
