Laser Marking of High-Reflectivity Metals: Copper, Gold, and Silver

In the field of laser marking, high-reflectivity metals such as copper, gold, and silver have always been a “challenge.” Why? Because they have extremely low absorption rates for conventional 1064nm fiber lasers — most of the laser energy is reflected away. Not only does this result in poor marking quality, but the reflected light can …
