Fiber Laser Marking Service Bureau · Twin Cities, MN
Dedicated fiber laser marking service bureau. MOPA laser for UDI, serialization, and laser annealing on stainless steel, titanium, and medical-grade plastics.
Same-business-day quote response. First article inspection included.
Who We Serve
MOPA fiber laser produces true laser annealing on stainless steel and titanium — the black oxide mark required for UDI compliance and sterilization resistance. No material removal. Passivation layer preserved. Certificate of conformance available on request.
The OEM calls it out on the print. You need a marking vendor who can execute to spec, on time, without creating problems. We're a dedicated service bureau — not a side operation. Issue the PO with confidence.
Capabilities
Technology
Most laser shops use standard fiber or CO2 lasers. MOPA (Master Oscillator Power Amplifier) technology gives us precise pulse control — required for true laser annealing that produces a compliant, biocompatible mark without removing material or compromising the passivation layer.
If your OEM specifies laser annealing, a standard fiber laser shop cannot do it correctly.
Documentation & Compliance
Results
A manufacturer came to us with a white Delrin part that three other vendors had declared "unmarkable." Our MOPA laser with specialized surface treatment produced a permanent, high-contrast mark. The part shipped. That's the job.
