UV vs IR Laser Marking Comparison

This document compares ultraviolet (UV) laser marking to traditional infrared (IR) laser marking, highlighting UV's "cold marking" process that uses high photon energy to break molecular bonds directly, minimizing heat-affected zones and surface damage. It presents technical data on marking depth, absorption rates, and material compatibility, demonstrating UV lasers' advantages for metals, plastics, copper, paper, and stainless steel while preserving corrosion resistance.
