JPT M7 20–100W Series
MOPA (Master Oscillator Power Amplifier) · China — MOPA pulsed ytterbium fiber — Independently adjustable pulse width (2–500 ns) and frequency (1–4000 kHz). High frequency flexibility; pulse energy per pulse is lower than Q-switched at equivalent average power. — Widest pulse width range of any JPT M7 variant. Minimum 2 ns enables color marking on stainless steel and titanium — a capability unavailable on Q-switched architectures.
OEM Laser Source Module
This is a laser source module sold to system integrators — not a complete laser cleaning machine. Specifications reflect the bare source only. End-user systems built on this module will vary in beam delivery, scan head, and enclosure.
Derived Parameters
| Fluence at 2 mm spot | 0.0318 J/cm² |
