Aviation Laser Services © 2025 1. Optimal Range: Studies show 5 J/cm² is ideal for aircraft skin paint removal (Boeing BMS10-11 primer) 2. Warning Signs of Excessive Fluence: o Surface waviness or "petal" deformation increases o Substrate color changes (indicates reaching base metal) o Excessive heat buildup 3. Pulse Duration Adjustments: o 100-200 μs optimal for paint layers o Shorter pulses (100-150 μs) for thin coatings o Longer pulses (200-250 μs) for thick or stubborn coatings Recommended Test Progression: Start with Step 1, test on a sample area. If insufficient removal, progress to Step 2, and so on. Most users find optimal results between Steps 2 and 3. Note: The research indicates that excessive fluence (>6 J/cm²) can damage aluminum substrates, particularly around rivet areas where fretting fatigue is a concern.
