What really blows everybody away is how perfectly your system integrated with our database. Going into this project, the other companies we talked to just didn't get it. But you understood where we were going and what had to be done.
How MOPA marking works at Brady
You don't need to know the exact pulse-duration, frequency, or fluence yet. That's our job - your part is the proof.
Fill out the form or call. Material (anodized aluminum, titanium, stainless, coated, thin-wall...), geometry, mark type - that's all we need to get started.
We MOPA-mark your actual part across multiple pulse-duration and frequency settings, plus a comparison fiber mark, then send it back with a full feasibility report.

Why MOPA fiber laser marking
MOPA fiber lasers solve marking problems that standard fiber lasers can't. Pick your challenge to see the application, the MOPA-specific solution, and proof it works.
A standard CW fiber laser runs at a fixed pulse duration (≈100 ns) and high peak power. On thin-wall parts, anodized aluminum, painted surfaces, or sensitive substrates that creates a wide heat-affected zone (HAZ) - warping, discoloration, surface charring, or coating damage. The mark is visible, but the part is no longer acceptable.

Standard fiber lasers ablate the anodized layer on aluminum, leaving a gray etch that breaks the surface treatment. They can't reliably produce color marks on stainless or steel. For brand-critical surfaces - consumer electronics, medical instrument handles, aerospace nameplates, automotive interior trim - the result looks unfinished. You need marks that are permanent and beautiful.

Medical implants need UDI Data Matrix codes that survive sterilization without compromising the substrate. Electronics and PCBs need traceable serials marked without thermal damage to nearby components. Painted, plated, and thin-wall parts need permanent marks that don't crack the coating or warp the substrate. Standard fiber lasers are too hot for the job.

A standalone MOPA laser on a benchtop solves the marking-quality problem - but if it can't pull serial numbers from your ERP, talk to your PLC, and verify the mark before the part moves down the line, you've just added a manual step. You need the MOPA fiber laser and the integration around it.

Send Us Your Part - FreeMOPA Fiber Laser FAQ
MOPA-specific answers from our applications engineering, integration, compliance, and field service teams - including the uncomfortable ones. If your question isn't here, send us your part and we'll answer it one-on-one.
A standard Q-switched fiber laser has a fixed pulse duration (typically around 100 ns) and a fixed relationship between peak power and pulse frequency. You can change power and frequency, but not the pulse shape.
A MOPA (Master Oscillator Power Amplifier) fiber laser separates the pulse-generating stage (oscillator) from the amplification stage. That means pulse duration is independently adjustable - typically anywhere from 1 ns to 200 ns - and frequency can reach up to 1 MHz. You can dial in short pulses for low heat input and high peak power, or long pulses for deeper marks. Same wavelength (1064 nm), same beam path, vastly more control.
In practical terms: MOPA can produce color marks on stainless and steel, black marks on anodized aluminum without removing the coating, low-HAZ marks on thin-wall and sensitive parts, and photo-quality grayscale - all on the same machine. A standard fiber can't do any of those reliably.
Yes - this is the application MOPA was built for. MOPA's short-pulse settings anneal the aluminum substrate beneath the anodized layer rather than ablating the coating, producing a jet-black, high-contrast mark while the anodization stays intact.
A standard fiber laser will burn through the coating and expose bare aluminum - a gray, etched, unfinished-looking mark. Send us your anodized part and we'll run a MOPA vs. standard-fiber side-by-side so you can see the difference before you specify equipment.
Yes. By tuning the pulse duration, frequency, and fluence, MOPA controls the oxide-layer thickness that forms during marking. Different oxide thicknesses refract light at different wavelengths, producing visible color.
On stainless steel and titanium you can reliably achieve black, amber, blue, green, and silver from the same machine. Repeatability depends on the substrate finish and alloy - we calibrate the parameters for your specific material when you send us a sample.
One note on durability: color marks are surface oxide layers, so they're best for visible/branding marks rather than marks that need to survive aggressive post-process (heat treat, acid passivation). For permanent traceability on the same machine, switch back to the standard MOPA black/gray mark.
Yes - MOPA is the typical recommendation for UDI marking on titanium and stainless steel medical devices. The reasons:
Send us a sample implant and we'll mark it with MOPA, dot-peen, and standard fiber so you can specify the right method - and see the difference under a stereo microscope.
Yes. BAE Systems uses our fiber laser and dot peen systems for Bradley vehicle component marking under MIL-STD-130N. For coated, painted, or sensitive substrates that a standard fiber would damage, MOPA delivers the same compliant 2D Data Matrix with controlled heat input.
We size the Data Matrix per the standard, encode Issuing Agency Code + Enterprise Identifier + Serial Number per Construct 1 or 2, and verify with Cognex to AIM DPM-1-2006 Grade B or better. MIL-STD-130N Change 1 syntax is supported. If you're supplying to a specific DoD program with supplementary requirements, send us the contract data requirement and we'll match it.
Honest answer: it depends far more on how you deploy the system than on the laser itself. A MOPA source is a premium configuration - the pulse-control hardware costs more than a basic fixed-pulse fiber - so it won't be your cheapest option, but the bigger price drivers are wattage, enclosure class, verification, and automation level.
The main cost tiers, lowest to highest:
We don't hide behind "contact us," but we also won't quote a number that misleads you - the spread across those tiers is real. Send us your part and your production context and we'll scope a configuration and quote it explicitly, itemized.
Typical turnaround is 3-5 business days from the day your part arrives at our Cranberry, PA applications lab. That includes marking your part with multiple MOPA pulse-duration, frequency, and power settings; photographing the results; writing the feasibility report with the parameters that worked; and shipping the part back with sample marks.
One anodized aluminum, titanium, stainless, or thin-wall part is enough for a basic MOPA feasibility test. Three to five with different finishes is ideal. A Brady Marking applications engineer follows up within 1 business day of form submission.
