P-Laser QF-300 Laser Cleaning Parameters
High-Energy Q-Switched. Fixed pulse width, very high pulse energy (10–100 mJ). Optimized for interfacial detachment of thick coatings. Pulse width is not operator-adjustable.
Derived Parameters
| Peak power | 600 kW |
| Fluence at 2 mm spot | 1.91 J/cm² |
| Fluence at 5 mm spot | 0.306 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.
Derived from manufacturer pulse energy data. Spot size varies by scan head — validate against your calibration.
