IPG Photonics YLP Series
Standard Q-Switched · USA / Germany — MOPFA / Q-switched pulsed ytterbium fiber — Fixed pulse width (typically 80–200 ns), adjustable frequency within narrower range than MOPA. Lower pulse energy ceiling than high-energy Q-switched. — YLPN series spans multiple sub-families. YLPN-M modules: ≤500 W, air-cooled, ≤2 mJ, 0.15–500 ns. YLPN-R/S cabinets: up to 2–3 kW, water-cooled, up to 100–150 mJ, 0.15–2000 ns.
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 | 4.77 J/cm² |
| Fluence at 5 mm spot | 0.764 J/cm² |
| Overlap (cleaning) | 60–80% |
Field spot diameter varies by scan head — 2 mm and 5 mm are representative values for handheld cleaning heads.
