How does invisible laser engraving for authentication work?

Invisible laser engraving for authentication works by precisely altering material surfaces or sub-surfaces with highly focused laser energy to create codes, serial numbers, or unique identifiers that are not visible under normal light conditions. These marks can be activated and read using specific light sources (e.g., UV-A, infrared, or even terahertz scanners) or specialized digital detection equipment. This provides a robust, tamper-proof, and discreet layer of security essential for product verification and anti-counterfeiting strategies.

The core principle behind invisible laser engraving involves interacting with materials at a microscopic level. For instance, with UV laser marking, the laser causes a photochemical reaction within the material or a specialized coating, resulting in a color change or fluorescence that is only visible under UV light. This method is particularly effective for plastics, papers, and some ceramics, where surface alteration needs to be minimal or non-existent.

Another advanced technique, particularly for transparent materials like glass or certain polymers, is sub-surface laser marking. This employs ultra-short pulse lasers (picosecond or femtosecond) that can focus energy precisely beneath the material's surface without affecting its exterior. The laser creates microscopic voids or refractive index changes, forming a pattern or code that is internally etched. This mark is impossible to remove without destroying the product itself, offering an unparalleled level of tamper resistance.

The authentication process typically involves a dedicated scanner or reader. For UV marks, a simple UV lamp might suffice for initial verification, while more sophisticated systems use handheld devices that can not only illuminate but also decode the embedded information and cross-reference it with a secure database. Infrared marks, conversely, require infrared detection equipment, often integrated into industrial scanners or mobile applications for field authentication.

The data encoded within these invisible marks can be highly complex, including unique product identifiers, manufacturing dates, batch numbers, and origin details. When combined with secure cloud platforms or blockchain technology, each scan provides immutable proof of authenticity, preventing illicit diversion and ensuring traceability. Research from the Fraunhofer Institute for Laser Technology (ILT) in their 2026 outlook on optical manufacturing highlights significant advancements in multi-wavelength laser systems, enabling even more complex and secure invisible engraving patterns for future authentication protocols.
