P-Laser QFC-50
Standard Q-Switched · Belgium — Q-switched nanosecond pulsed fiber — Fixed pulse width (typically 80–200 ns), adjustable frequency within narrower range than MOPA. Lower pulse energy ceiling than high-energy Q-switched.
Derived Parameters
| Fluence at 2 mm spot | 0.0318 J/cm² |
| Fluence at 5 mm spot | 0.00509 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.
