MOPA MFPT 70M Pulsed Fiber Laser

The MFPT 70M steps up from the MFPT 20M/30M/50M/60M group into a larger miniaturized chassis, built for marking, engraving, and low-heat micro-welding. At 70W, it runs in CW or pulsed operating modes with beam quality of M² ≤1.4 and a wider repetition rate range of 1 to 8000kHz — double the smaller group's 4000kHz ceiling — for finer control across the wider range of processes this tier supports.

Output is tunable from 10% to 100% of rated power, with single pulse energy of 1.1mJ for switching between surface marking, micro-cutting, and low-spatter welding without changing hardware. It offers a choice of fiber output — a fixed isolator or a QCS quick-connect — runs on air cooling, drawing 360W from a 24VDC supply, and ships CE-certified with a 2-year standard warranty, extendable up to 5 years.

Key Features

M² ≤1.4 Beam Quality

A beam quality of M² ≤1.4 keeps the focused spot fine and consistent, for legible marks and clean engraved detail.

1–8000kHz Repetition Rate

A wider repetition rate range than the MFPT 20M/30M/50M/60M group, adjustable from 1 to 8000kHz, for finer control across marking, micro-cutting, and welding work.

Marking, Micro-Cutting, and Low-Spatter Welding

Tunable heat input lets the MFPT 70M switch between surface marking, micro-cutting, and low-spatter welding without swapping hardware.

Isolator or QCS Fiber Output

Available with a fixed isolator output or a QCS quick-connect output, for flexibility in how the laser integrates into a production line.

Air-Cooled, No Water Loop Required

Runs on air cooling rather than a closed water loop, simplifying installation for bench-top, mobile, or OEM integration.

Larger Chassis for the Power Step-Up

At 290 × 235 × 100mm and roughly 6.5kg, the MFPT 70M steps up to a larger miniaturized chassis than the MFPT 20M/30M/50M/60M group, shared with the MFPT 100M.
