Heat accumulation
Impact: Excessive heat can damage substrate or alter material properties
Solutions:
- ✓Reduce repetition rate
- ✓Increase scan speed
- ✓Add cooling time between passes
Prevention: Monitor surface temperature and adjust parameters accordingly
🔍surface characteristics
Variable surface roughness
Impact: Inconsistent cleaning results across different surface textures
Solutions:
- ✓Adjust energy density based on surface condition
- ✓Use multiple passes with progressive settings
- ✓Pre-characterize surface before cleaning
Prevention: Standardize surface preparation procedures

Parameter Relationships
Shows how changing one parameter physically affects others. Click any node to see its downstream impacts and role.
Power Range
Amplifies damage risk in Pulse Width and Energy Density. Keep low to maintain safety margins.
Spot Size
Same power in a smaller spot creates much higher energy density.
Energy Density
Higher power delivers more energy per pulse, removing more material.
Pulse Width
More power means higher peak intensity. Too much can damage the material.
Pass Count
Using more passes means you can use lower power and still get the job done.
