Why MOPA Matters

UN Master Oscillator Power UNmplifier (MOPA) fiber laser differs from a standard Q‑switched laser by letting you tweak the pulse duration (Q‑pulse width) and frequency independently. That means:

• Marcatura a colori on stainless steel without coatings
• Fine Detail on reflective metals and plastics
• Incisione profonda on brass coins and heavy metals
• Minimal Heat‑Affected Zone for delicate substrates

Pair that with 60 W of laser power and you’ve got a workhorse that handles both micro‑precision and industrial tasks.

Fiber Laser Engraver Key Parameters Explained

Before diving in, here’s what each setting does:

• Energia (%): Laser output intensity (0–100%).
• Velocità (mm/s): Head travel rate; slower speeds deepen cuts or marks.
• Frequenza (kHz): Pulse repetition rate; higher frequencies smooth edges on metals.
• Q‑Pulse Width (ns): Pulse duration; longer pulses deposit more energy per pulse.
• Line Interval/Space (mm): Raster spacing for engraving; smaller values increase resolution.
• Passa: Number of times the laser repeats the same path for deeper cuts or darker marks.
• Modalità tratteggio / Image Mode: Controls fill patterns (per esempio., cross‑hatch, 3D slice, threshold dithering).
