JPT MOPA 30W Fiber Settings & Speeds

Removes coating cleanly. Test on scrap first to confirm full removal.

Clean coating removal. MOPA gives sharper mask edge than Q-switch.

Bright silver on black oxide. MOPA gives sharp contrast.

Fast white mark on aluminum dog tags. MOPA precision is excellent.

Bright white mark on aluminum keychains at speed.

Clean batch marking on keychains.

Permanent ID mark. MOPA produces consistent black across batches.

Very low power on gold-filled. MOPA short pulse protects thin gold layer.

Sharp detail on chrome lid. MOPA preserves plating integrity.

White mark on aluminum. Clean result at high speed.

Ultra-sharp lines. MOPA allows <0.1mm feature size.

Permanent logo/serial on blade. MOPA mark won't rust.

Fine detail on silver. MOPA keeps heat low for intricate designs.

Deep permanent mark. Rotary needed. 0.04mm fill for solid blacks.

MOPA gentle on chrome. Short pulse keeps plating intact.

Permanent dark mark on nickel. MOPA avoids chipping plating.

Peels coating cleanly. MOPA gives sharper edge than standard fiber.

Clean coating removal. Rotary required. MOPA gives sharper edges.

High power needed for copper. Dark brown-black result.

Dark mark on brass. MOPA allows finer detail than Q-switch.

Brilliant white on black anodized. MOPA minimizes heat spread.

MOPA pulse control gives very crisp white on black anodized.

Deep blue color mark. MOPA excels at titanium color marking vs regular fiber.

Black oxidation mark. MOPA pulse width 4ns for darkest result.

Low power to avoid damaging base metal fill. Test on scrap first.

Black anodize gives best white contrast — popular for dog tags and keychains.

Copper is reflective — fiber can damage tube at high power. Keep below 80% and test carefully.

MOPA pulse width controls colour: 2ns=dark blue, 50ns=gold, 100ns=purple.

Deep engrave: 50kHz, 4ns pulse. Multiple passes for depth.

MOPA: set pulse width 2ns for dark mark, 200ns for bright silver. Adjust pulse frequency 20-80kHz.

What materials can the JPT MOPA 30W Fiber engrave or cut?

The JPT MOPA 30W Fiber has community-tested settings for Slate, Coated / Powder Coated Steel, Powder Coated Aluminum, Black Oxide Stainless Steel, Aluminum Dog Tag, Aluminum Keychain, Stainless Steel Keychain, Stainless Steel Dog Tag, and 18 more. Results vary by material batch, focus, and ambient conditions — always test on scrap first.

Can the JPT MOPA 30W Fiber mark bare metal without any coating?

Yes. Fiber lasers mark stainless steel, brass, copper, titanium, and anodized aluminium directly — no Cermark or marking spray needed. This is the main advantage of fiber over CO₂ or diode machines for metal personalisation.
