Meaning
Precision engraving techniques using ultra-short laser pulses create permanent marks on a surface without generating significant heat. Utilization of picosecond laser marking allows for the high-resolution labeling of sensitive components that could be damaged by traditional thermal methods. The process creates a mark by altering the surface structure at the molecular level, resulting in a high-contrast image that is difficult to forge.
This technology is widely used for branding and serializing medical devices and electronic parts.
Mark Integrity
Bursts of light lasting only a few trillionths of a second ensure that the surrounding material remains cool. This prevents cracking or warping in delicate substrates like glass or thin polymers.
Counterfeit Deterrence
Microscopic identifiers can be embedded into the surface to verify the authenticity of a product. Because picosecond laser marking requires expensive and specialized equipment, it is a significant barrier for counterfeiters trying to replicate a brand. The marks are resistant to chemicals and abrasion, ensuring they remain readable throughout the life of the product.
This permanence is vital for tracking components in the event of a recall. Logistics systems use these marks to scan items at every point in the distribution chain.
Surface Stability
Maintaining the physical properties of the component is the primary goal of this cold marking process. picosecond laser marking provides a clean and precise finish without the need for inks or solvents.
