Mopa Fiber Laser Color Marker for Colored Marking on Stainless Steel

The laser generator of the MOPA fiber laser color marking machine adopts MOPA technology, which is characterized by the precise adjustment of pulse duration, pulse repetition rate, and pulse energy. By setting appropriate parameters, a controllable thickness of oxide film can be formed on specific metal surfaces. When light is incident, the oxide film refracts or absorbs certain wavelengths, causing the reflected color to change. This device can perform multi-color marking on specific metal materials such as stainless steel, aluminum, chromium, and titanium, providing a new alternative to chemical coloring or anodizing.
