ComMarker Laser Engravers

A MOPA fiber laser lets you adjust pulse width independently of power, which enables color engraving and finer depth control on stainless steel, titanium, and aluminum — a capability a standard fiber laser doesn't have. That independent pulse control changes how heat enters the metal, which is what produces the blues, golds, and other colors on stainless steel rather than just a single-tone etched mark. MOPA models typically carry a meaningful price premium over standard fiber lasers at the same wattage, but for makers selling branded or decorative metal goods, that color capability adds a level of finish standard fiber can't match. ComMarker offers MOPA specifically because color marking and precise depth control are the features that matter most to jewelry makers and custom branding shops.

Yes — ComMarker's fiber laser engravers mark bare stainless steel, titanium, aluminum, brass, and copper directly, producing deep, high-contrast results with no spray coating or pre-treatment needed. Fiber laser wavelengths are readily absorbed by bare metal, so the beam generates enough localized heat to oxidize or vaporize the surface without needing a marking spray as an intermediary the way CO2 or diode lasers do. ComMarker's fiber models typically run 20W to 60W, with higher wattage cutting engraving time down and improving contrast on harder metals like titanium. Skipping the coating step also means less mess and no waiting on spray to dry between engraving passes.

ComMarker machines like the B6 MOPA are dedicated fiber engravers built for depth and color control on metal, while dual-laser machines add a diode module for wood, leather, and other organics at the cost of MOPA color capability. A dual-laser machine trades some of that metal-marking precision for material versatility, making it a better fit for makers splitting time between metal and organic materials in one machine. ComMarker's dedicated fiber focus, by contrast, is built for shops doing metal marking as their primary work, where color depth and mark consistency matter more than cutting wood or leather. Choosing between them mostly comes down to whether metal marking is the main job or one of several materials being worked.
